None of the answers is correct Bcos we are not all calculating interest instead we are caluculating the total amount for 1 year under simple interest with rate of interest is already converted into decimal form.

Eg:if rate of interest is some 6% then her  it is taken  as 0.06.

The code simply calculates the compound interest for max four years
It is so bcoz of absence of break statement in the switch.
