Answer:
2) the M-2 money supply has increased, but the M-1 money supply was stable.
Explanation:
Monet market funds and certificates of deposits are included in the M2 money supply.
Since all the other major components of the money supply, both M1 and M3, remained unchanged, then only M2 has increased.
M2 includes M1 + savings accounts, certificates of deposits and money market funds.
