D?
I solved this by plugging in. If y is 5, then A is greater but if Y is 4.1, then B is greater. Hence, D.

yLet's use the strategy of Matching Operations
Given:
Quantity A: (3y + 2)/5
Quantity B: y
Multiply both quantities by 5:
Quantity A: 3y + 2
Quantity B: 5y
Subtract 3y from both quantities:
Quantity A: 2
Quantity B: 2y
Divide both quantities by 2:
Quantity A: 1
Quantity B: y
Since we're told that y > 4, we can be certain that Quantity B is greater.
