Answer:
The correct answer is letter "A": Determining other purchase decision influencers.
Explanation:
While engaging prospective buyers into a purchase, salespeople should be aware of what the consumer is looking for. Different consumers have different preferences such as price, brand, quality, technical features, or useful life. Then, once the purchase decision influencer has been identified, clerks must focus on that characteristic to attempt closing the sale.
Thus, Carlos must review his sales speech and pay special attention to what customers are looking for to determine which purchase decision influencer they are related to.
