Question : A firm’s supply curve is on an upward slope because:-
A: The production costs of additional units of output will rise beyond a point
B: Consumers see a positive relationship between price and quality
C: Expansion of production leads to the use of inferior inputs
Option 1: A only
Option 2: C only
Option 3: B only
Option 4: A, B and C all
Correct Answer: C only
Solution :
The perception that the marginal benefit of producing the good has increased is what causes the supply curve's upward slope - in other words, the higher price required to cover the higher marginal cost of production slopes the curve upward.
Expansion of production leads to the use of inferior inputs.
Hence c is the correct answer
