Correct Option: B. Offering free samples Explanation of Why the Answer is Correct: Sales promotion refers to various marketing strategies aimed at increasing the sales of a product or service in the short term. It often involves incentives that encourage customers to make a purchase. Offering free samples is a classic example of a sales promotion technique. Here’s why:

1. Immediate Incentive: Free samples provide customers with an immediate incentive to try a product without any financial commitment. This can lead to increased interest and potential future purchases.
2. Product Experience: By allowing customers to experience the product firsthand, free samples can help overcome any hesitations or doubts about the product's quality or effectiveness. This is particularly important for new products or brands that consumers may not be familiar with.
3. Encouraging Word-of-Mouth: When customers receive a free sample and enjoy the product, they are more likely to share their positive experience with friends and family, leading to organic promotion and potentially more sales.
4. Targeted Marketing: Free samples can be strategically distributed to target specific demographics or locations, making them an effective way to reach potential customers who are most likely to be interested in the product.

Explanation of Why the Other Options are Wrong or Weaker:

• A. Advertising on radio:
• While radio advertising is a form of promotion, it is primarily a method of raising awareness rather than a direct sales promotion. It does not provide an immediate incentive for customers to purchase a product. Instead, it aims to inform and persuade potential customers over time.
• C. Distributing printed materials:
• Similar to radio advertising, distributing printed materials (like brochures or flyers) serves more as an informational tool rather than a direct sales promotion. While it can help in creating awareness and interest, it does not offer an immediate incentive for customers to buy the product.
• D. Advertising on television:
• Television advertising is another form of promotion that focuses on brand awareness and product visibility. Like radio advertising, it does not provide an immediate incentive for purchase. It is more about reaching a broad audience and building brand recognition over time.

Summary of Key Points:

• Sales Promotion: Aimed at increasing short-term sales through incentives.
• Free Samples: Provide immediate, risk-free product experience, encouraging purchases.
• Other Options: Radio and TV advertising, as well as printed materials, focus on awareness rather than direct incentives for purchase.
• Effective Strategy: Free samples can lead to word-of-mouth promotion and targeted marketing success.
