Answer: Option B
Explanation:
Given expression:

To find the simplified form of the given expression
We know, x to the power 0 is equal to 1. i.e.
. Therefore, it gets removed in the given expression.

As common ‘4’ in numerator and denominator also gets cancelled in the given expression

Bring negative exponents (in numerator) down (to denominator) to form positive exponents, we get the simplified form of given expression as below,
