Answer:
A). Drop.
Step-by-step explanation:
Controlling the interest rates is one of the vital element of government's fiscal policy that it applies to stabilize the economy during recession or inflation.
As per the question, the economic rates must be 'dropped or lowered' during a recession in order to increase the supply/flow of money in the market that would comprehend higher disposable income and improved economic activities that would assist in bringing the economy to the equilibrium.

In order to control this, the government lowers tax rate(as a part of its fiscal policy) to increase investment and work opportunities for people that would comprehend the flow of money in the market and stabilize the economy. Thus, option A is the correct answer.
