Shocks to the Economy Often Result in Calls for Government

Shocks to the economy often result in calls for government action to correct the imbalances these shocks create. Why don't markets tend to correct these imbalances quickly by themselves?

A) Prices adjust too quickly for markets to correct imbalances.
B) Government policy is the primary cause of shocks, so government policy is the only way to correct the imbalances they create.
C) Buyers and sellers in markets don't react rationally when shocks occur.
D) Product prices are often "sticky" or inflexible, keeping markets from correcting imbalances quickly.
