Explanation / Answer

In case of Company A:

37000 is 2 standard deviation above mean ( 31000 +2*3000)

In case of Company B:

37000 is less than 1 standard deviation above mean (< 31000 +1*7000)

Since Z for B is smaller than Z for A, we say that option C is right.

It' easier to cover 1 standard deviation than 2 deviations. That' what C says
