What is the answer and how do i solve ?

The correct answer would be C. None of the above

Here’s how you solve it!

First remove the parentheses so your expression will look like this:

-6-12+4n

Then collect like terms which is -6n and 4n so that you are left with this:

-2n-12

Now you factor out -2 from the expression to get your finally

-2(n+6)

This answer is similar to option B however it is positive while option B is giving you a negative sign.

Hope this helps! :3
