What does 'minimum' mean?

• A. the smallest size possible
• B. the largest size possible
• C. the smallest or least amount of something possible
• D. a calculation unit

Answer: (C)

Minimum refers to the smallest amount, degree, or value that is allowed or possible. It describes the lower limit you can’t go below in a given context. In everyday use you’ll see it in phrases like minimum wage, minimum age, or minimum requirements—each pointing to the least you must have or the least you must do.

That breadth is why the best option is the one that states the smallest or least amount of something possible. The other choices miss the core idea: saying the largest value points to the opposite concept (maximum); focusing only on size narrows the meaning; and a calculation unit isn’t related to the idea of a lower bound.
