Answer:
Option D. i is the correct option.
Step-by-step explanation:
The given expression is in the form of ![i^{20+1}](https://tex.z-dn.net/?f=i%5E%7B20%2B1%7D)
expression can be written as
as pwers get added when multiplied.
Now we know
Or
then we will try to convert the expression in the form of i².
![(i^{2})^{10} .i = (-1)^{10} .i=[(-1)^{2}]^{5}.i=1^{5}.i=1.i=i](https://tex.z-dn.net/?f=%28i%5E%7B2%7D%29%5E%7B10%7D%20.i%20%3D%20%28-1%29%5E%7B10%7D%20.i%3D%5B%28-1%29%5E%7B2%7D%5D%5E%7B5%7D.i%3D1%5E%7B5%7D.i%3D1.i%3Di)
Therefore option D is the answer.
