Identifying efficient production on the PPC

Steps:

• Recall that the PPC shows maximum combinations of two goods producible with fixed resources.
• Points on the curve represent efficient production (full resource use).
• Points inside the curve are inefficient (underutilized resources).
• Points outside are unattainable with current resources.

Why C is correct:

• Option C is on the PPC, indicating efficient and attainable production per the definition of opportunity cost and resource allocation.

Why the others are wrong:

• A is inside the curve, showing inefficient production.
• B is outside the curve, unattainable without growth.
• D misinterprets the curve's slope as constant returns.

Final answer: C
