Step-by-step explanation:

A.

Step-by-step explanation:

We have been given an expression . We are asked to simplify our given expression.    

We will factor the denominators of both fractions as shown below:    

Splitting the middle term.

 Making groups.

 Factor out 4r from 1st group.

 Factor out 1 from 2nd group.

Using difference of squares we will factor the 2nd denominator as:

Substituting these values in our given problem we will get,

After cancelling out terms we will get,

Therefore, option A is the correct choice.
