Answer:
C 21.55%
Step-by-step explanation:
The investment grows by 5% in three months and assuming that the investment earns 5% for every three months (every quarter). Therefore every quarter investment earns 5%. The annualized return is calculated as follows:
Annualized return = (1 + periodic return) * (1 + periodic return).... -1 * 100
Annualized return =( 1.05 * 1.05 * 1.05 * 1.05) - 1 * 100
Annualized return = 21.55%
