Answer:
adaptive
Step-by-step explanation:
A product is sold to a customer keeping in mind what the expectations of the customer i.e., the customer tries to fulfill the needs of the customer.
It can be seen here that Scott noticed the non verbal cues from his customer. He deduced that the owner did not like his design of the window. He then suggested a different design. He adapted according to the needs of the customer on the spot.
Hence, this type of selling is called adaptive selling.
