Answer: Second option is correct.
Explanation:
Since we have given that

And 
To find the remainder, we use the Remainder Theorem, which states that when f(x) is divided by (x-c) then the f(c) is the required remainder.
So,
Here, we have,

So, we will find f(-2) which will give us the required remainder,

Hence, Second option is correct.
