Answer:
D. A decrease in supply and a shift to the left of the supply curve
Explanation:
An increase in the cost of an input is an increase in the total cost of production of a good or service. If for producers is more expensive to produce, they will produce less, and the result is a decrease in the supply of that good or service. In the Demand and Supply curve, for each price there will be less quantity supplied. This looks as a shift to the left of the supply curve.
