Answer:

Step-by-step explanation:
We want to evaluate the following limit.

We need to recall that, limit of a sum is the sum of the limit.
So we need to find each individual limit and add them up.

Recall that, as  and the limit of a constant, gives the same constant value.
 and the limit of a constant, gives the same constant value.
This implies that,

This gives us,

The correct answer is D
