Answer:
Letter A
the demand would be represented by boat owners wanting boat repairs, while supply is represented by boat body shops and glass repair and replacement companies.
Explanation:
A "supply" refers to providing goods to people. Most of the time, these goods are what people want. A "demand" refers to the desire of a consumer to purchase a good or a service.
In the situation above, the tsunami damaged thousands of boats. So, this means that the demand for "boat repairs" will increase. Such repairs will be accommodated by a supply of goods and services offered by boat body shops, glass repairs and replacement companies.
So, this explains the answer.
