Which situation describes a tie-in agreement?

A tie-in agreement is a specific type of arrangement where the sale of one product is conditional upon the purchase of another product. This means that the buyer must agree to buy an additional product that is often related to the primary product in order to complete the purchase. Such agreements can create dependency between products and may be used to promote sales of an additional item that the seller wants to push in the market.

In this scenario, choosing a conditional sale linked to another purchase directly captures the essence of a tie-in agreement, as it highlights the requirement that is central to such arrangements.

The other situations do not fit the definition of a tie-in agreement. Discounts for bulk purchases relate to pricing strategies that incentivize larger quantity buys but do not tie one product's sale to the purchase of another. Exclusive distribution agreements deal with the restrictions on selling products and provide exclusivity to certain sellers but do not involve conditional purchases of linked products. Sales at below market rates are pricing strategies and do not establish any requirement or condition for purchasing another item, thus not aligning with the concept of a tie-in agreement.
