Answer:
The correct answer is d) The factor supply curve in an industry will shift to the left as wage rates in that industry rise.
Explanation:
The demand for factors is based in the demand for the goods and services that are produced using these factors and if the demand for the source good decreases, the demand for the production factor will also decrease.
In this case, when the market wages increase, the ability of suppliers to use labor goes down and as a result the demand curve will shift left.
