Answer:
Option D is correct that is (-4,-11).
Step-by-step explanation:
We have been given an expression:

We need to find the points of discontinuity
We will first factorize the given expression



Hence, the point of discontinuity is where denominator gives value zero
So, 
Point of discontinuity is -4
hence, after removing the point of discontinuity the function left is:

Hence, put x=-4

Therefore, option D is correct that is (-4,-11).
