Question

Quizplus · Accepted Answer

A movement along a supply curve occurs when there is a change in the quantity supplied due to a change in the price of the good itself, which is described in option C. Changes in costs of production, expectations about future prices, or prices of substitutes in production would cause a shift in the supply curve, not a movement along it.
