Finite resources are non-renewable

Steps:

• Define finite resource as one with limited supply that cannot be replenished naturally within human timescales.
• Evaluate choice A: Matches definition by stating it does not renew itself.
• Check other choices: B relates to scarcity, not finiteness; C ignores economic costs; D contradicts limited supply.
• Confirm A as the identifier based on standard resource classification.

Why A is correct:

• Finite resources, by definition in economics and environmental science, are non-renewable, meaning they do not regenerate naturally, like fossil fuels.

Why the others are wrong:

• B: Supply exceeding demand describes abundance, not finiteness.
• C: All resources have opportunity costs; this does not define finiteness.
• D: Unlimited supply identifies infinite resources, opposite of finite.

Final answer: A
