Answer:
c. wages and prices are often inflexible in the downward direction
Explanation:
While the prices of the products can decrease in a recession when there is a decrease in demand there is an excess in the supply, therefore, the price decreases but, in real life that doesn't occur people prefer not to work rather than going to work for a lesser amount most of the times. The same goes for some prices under which the producer or manufacture firm does not reduce the price.
