Answer:
A, B and D
Step-by-step explanation:
Expanding the money supply is an exercise of expansionary monetary policy.
This decision will first allow our tech startup to acquire cheaper loans and expand our operations, this expansion in operations will result in new employment opportunities and hence as a result, unemployment will be reduced assuming this is a general trend in the economy.
This decision also directly reflects an increased investment and hence the GDP on the whole and the investment part of GDP would both increase,
GDP = C + I + G + (X - M), where I = investment.
This change in macro economy will increase aggregate demand due to expansionary effects. Increase in imports is not conclusive as it may or may not happen depending upon the demand state.
Hope this helps.
