Answer :
Answer:
B
Explanation:
I think you've already figured this out for yourself, but I thought I'd answer anyway and maybe clarify some things.
Supply is the total amount of a good or service that is available to consumers.
- Think about it: goods are physical things bought and sold, like apples. Services are actions done for another person, like taxi driving or renting a used car.
- None of the other answers make sense: a "device" is not a strictly defined term in economics; an "industry" can't be available to consumers, and a "warranty" isn't applicable.
