If I'm not mistaken the answer would be B. You need to make the fractions equal in the bottom number which is 10. The fraction 3/5 and 1/2 have the same common number of 10 so you'd times both fractions witch would give you 6/10 of angels cake and then 5/10 of how much he gives. So you half angels cake now sense it's that's what the question is asking and it would give 3/10.
