Answer:

The correct option is F.

Step-by-step explanation:

Consider the provided information.

i^n=1

It is given that i^2=-1

By squaring both sides we get,

(i^2)^2=(-1)^2

i^4=1

Now compare i^4=1 with the provided equation i^n=1.

By comparison, it can be concluded that n = 4.

Now, consider the provided option.

In each option, we need to divide n by 4 or we can say 4 divided by 4.

If we divide 4 with 4 it will give the remainder 0.

Therefore, the correct option is F.
