Roseann is x years old
Say Tom is y years old
In 2 years, Tom's age = y+2
So x = y+2-6 = y-4 or, y = x+4
So 3 years ago, Tom's age was = x+4-3 = x+1
(C) is correct

Ok so if tom's age is X,
And Roseann age is Y
(x+2)-6 = y
so y = x-4
y-3 = x-7
3 years ago, Roseann was y-3 and Tom was X-7
Answer is A) (just switch my Xs and Ys)
Sorry I used tom as X and Roseann as Y.
And Roseann age is Y
(x+2)-6 = y
so y = x-4
y-3 = x-7
