Decisions by the coffee collective regarding which type of organic dog biscuit to offer is an example of which element of retail strategy?

The correct answer is "merchandise." "Merchandise" signifies the products that a company sells and that customers buy. Since the collective's focus is on which type of biscuit (not on the location of the store, or on the dog owners, or on the price of the biscuits), the retail strategy element concerns these products, or merchandise.
