Final answer:
Promotions aimed at increasing product availability in distribution channels are termed trade sales promotions, focused on incentivizing channel partners rather than end consumers.
Step-by-step explanation:
Promotions designed to increase product availability in distribution channels are known as trade sales promotions. These types of promotions are targeted toward channel members like wholesalers, distributors, and retailers rather than the final consumer. The objective of trade sales promotions is to encourage these partners to stock up on the product, provide better shelf space, or promote the product more effectively through their channels. This can be achieved through various incentives such as discounts, allowances, free goods, or promotional support. On the other hand, consumer sales promotions are aimed directly at the end customers with the intention of triggering immediate sales.
The correct option is A) sales promotions.
