Answer :
C because if you want his age six years ago, you need to take his present age (A) and subtract 6

Six years ago, Roberts age was A - 6

If we look at the question, we are told that Roberts present age is A. Going by this we know that we are going to have to subtract 6 from his present age. We are subtracting because we are talking about the past. You should also know that the past means minus/subtract, future means addition.

Essentially, Roberts age 6 years ago is A - 6
