You just need to plug the value of n in your equation like this : 
-5 1/8 * 1 37/41 = -9 3/4 and see if it checks

these are my options
A. -6(2) = -12

B. -5(-2) = -10

C. -5(2) = -9

D. -5(2) = -10

Estimation means you round up to the nearest hole number. In our case : 
-5 1/8 ~ -5 and 1 37/41 ~ 2 and -9 3/4 ~ -10
So what option should it be ?

I gave you all hints so that all you have to do is replace. But anyways..
From  (-5 1/8) * (1 37/41) = (-9 3/4)
And    -5 1/8 ~ -5 and 1 37/41 ~ 2 and -9 3/4 ~ -10

We get -5 * 2 = -10
