Answer: Option (a) is correct.
Step-by-step explanation:
M1 consists of:
M1 = currency with the public + Check-able deposits + other deposits with RBI
M2 consists of:
M2 = M1 + post office savings bank account
If Joe transfers $1,000 from his savings account to his checking account, then there is a reduction in M2 and increase in M1. We know that M1 is a component of M2, therefore, M2 increases.
Hence, there is no change occur in M2 and M1 increases by $1,000.
