Final answer:
When a couple shows no intention of buying, it is best to ask them if there's anything specific they're looking for in order to gather more information and tailor your sales pitch. Hence, the correct answer is option (2).
Step-by-step explanation:
If you realize that a couple has no intention of buying soon after beginning your sales pitch, the most appropriate response would be to ask them if there's anything specific they're looking for. This approach allows you to gather more information about their needs and preferences, which can help you tailor your sales pitch accordingly.
By showing genuine interest in understanding their requirements, you may be able to address any concerns or misconceptions they have and potentially convert their interest into a purchase.
