Adecrease in the demand for pastry chefs may come about because of an:
a. increased concern for fitness.
b. increase in the market wage rate for pastry chefs.
c. increase in the supply of other factors that pastry chefs use.
d. increase in the productivity of pastry chefs.
e. decrease in the price of other factors that are employed with pastry chefs.

D) Increase in the market wage rate for pastry chefs.

Explanation:

A decreased demand may be caused by an increased wage rate of pastry chefs. Since a bakery may hire this expensive labor and produce pastries, this will result in increased cost for the bakery, this will be passed on to the consumers in turn for increased prices. Consumers will buy less of it and thus demand for pastries will fall requiring bakeries to hire less chefs.

Hope that helps.
