Correct Option: D Explanation of Why Option D is Correct: The Comprehensive Import Supervision Scheme (CISS) was established by the federal government of Nigeria primarily to ensure that imports into the country meet specific standards regarding quality, value, and quantity. This scheme is crucial for several reasons:

1. Quality Control: The CISS aims to prevent the entry of substandard goods into Nigeria. By enforcing quality checks, the government protects consumers from harmful or inferior products that could pose health risks or lead to dissatisfaction.
2. Value Assessment: The scheme helps in assessing the true value of imported goods. This is important for ensuring that import duties and taxes are accurately calculated, which in turn helps in generating revenue for the government.
3. Quantity Verification: Ensuring that the quantity of goods imported matches what is declared is vital for preventing smuggling and other forms of trade fraud. This helps maintain fair trade practices and protects local industries from unfair competition.
4. Regulatory Compliance: The CISS also ensures that importers comply with Nigerian laws and regulations, which is essential for maintaining order in the marketplace and protecting the economy.

Why the Other Options Are Incorrect: Option A: Reverse Nigeria's unfavourable balance of trade - While improving the quality and value of imports can indirectly affect the balance of trade, the primary focus of the CISS is not to reverse the balance of trade itself. The balance of trade is influenced by various factors, including exports, currency exchange rates, and global market conditions, making this option too broad and not directly aligned with the specific objectives of the CISS. Option B: Promote fair trade between Nigeria and other countries - Promoting fair trade is a noble goal, but the CISS is more focused on the quality, value, and quantity of imports rather than directly promoting fairness in trade relations. Fair trade encompasses a wider range of issues, including ethical sourcing and equitable treatment of producers, which are not the primary focus of the CISS. Option C: Counteract all fraudulent business deals of Nigeria with other nationals - While the CISS does help in reducing fraud related to imports, it does not address all fraudulent business deals in general. Fraud can occur in various forms and sectors, and the CISS is specifically tailored to import supervision rather than a comprehensive anti-fraud measure across all business dealings. Summary of Key Points:

• The Comprehensive Import Supervision Scheme (CISS) ensures that imports into Nigeria meet standards of quality, value, and quantity.
• It protects consumers from substandard goods and helps in accurate revenue collection through proper valuation.
• The scheme is not primarily aimed at reversing the balance of trade, promoting fair trade, or counteracting all forms of fraud.
• Understanding the specific objectives of the CISS is crucial for grasping its role in Nigeria's trade regulations.

This detailed understanding of the CISS will help you appreciate its importance in the context of international trade and commerce in Nigeria.
