Answer:
The correct answer is option d.
Explanation:
The economy is currently experiencing a high unemployment rate and weak economic growth. The inflation rate is low. In this situation to boost economic growth, the government needs to adopt an expansionary policy.
Buying government securities is an expansionary monetary policy. It would lead to an increase in the money supply. Commercial banks will be able to provide more credit.
Raising the reserve ratio will cause the excess reserves to decline. These two policy changes will thus offset each other.
