Correct Option: C. while it is fairly easy to control producers and importing firms, smaller distributors are too many to be controlled. Detailed Explanation: Price controls are government-imposed limits on the prices that can be charged for goods and services in a market. They are often implemented to protect consumers from high prices or to ensure that essential goods remain affordable. However, in the context of Nigeria, price controls face significant challenges, particularly due to the structure of the distribution system.

1. Understanding Price Controls:
2. Price controls can take the form of price ceilings (maximum prices) or price floors (minimum prices). While they aim to stabilize the market, they can lead to shortages or surpluses if not managed properly.
3. The Role of Distributors:
4. In Nigeria, the distribution network for goods is often fragmented. There are many small distributors and retailers who operate independently. This makes it difficult for the government to enforce price controls effectively.
5. Larger producers and importing firms can be monitored and regulated more easily because they are fewer in number and often operate under more formal structures. However, the sheer number of small distributors means that enforcing price controls on them is practically impossible.
6. Challenges of Enforcement:
7. Smaller distributors may not have the same level of oversight or regulation as larger firms. They can easily evade price controls by adjusting their pricing strategies or by selling goods in informal markets where regulations are less stringent.
8. This leads to a situation where even if the government sets a price limit, many consumers may still face higher prices due to the inability to control the multitude of small players in the market.
9. Consequences of Ineffective Price Controls:
10. When price controls are not effectively enforced, they can lead to unintended consequences such as black markets, where goods are sold at higher prices than the controlled price.
11. Additionally, producers may reduce supply if they cannot cover their costs at the controlled price, leading to shortages of essential goods.

Why Other Options Are Incorrect:

• Option A: the population is too large:
• While Nigeria does have a large population, this alone does not prevent price controls from working. Many countries with large populations successfully implement price controls. The issue is more about the structure of the market and enforcement rather than the size of the population.
• Option B: the policemen hate to arrest people:
• This option is overly simplistic and does not address the economic principles at play. The effectiveness of price controls is not primarily about law enforcement attitudes but rather about the feasibility of monitoring and regulating a large number of small distributors.
• Option D: control cannot work under military rule:
• While political stability can affect economic policies, the effectiveness of price controls is more about market structure and enforcement capabilities than the type of government in place. Price controls can be implemented under various political systems, but their success depends on the ability to enforce them.

Summary of Key Points:

• Price controls aim to stabilize prices but can lead to shortages if not enforced properly.
• The fragmented nature of Nigeria's distribution system makes it difficult to control numerous small distributors.
• Effective enforcement is crucial for price controls to work; larger firms are easier to regulate than smaller ones.
• Unintended consequences of ineffective price controls include black markets and reduced supply.

This understanding of price controls and their challenges in Nigeria is essential for grasping broader economic concepts and the implications of government intervention in markets.
