You mean you actually wanna get the correct answer and understand why as well? My hats off to you, matey! (..joking ..)

I don't know whether this helps but here are my notes on climbs;

The angle of climb depends directly on the amount of excess THRUST available and the weight of the aircraft.
The lower the weight, the greater the angle of climb
The greater the thrust, the greater the angle of climb
The lower the drag, the greater the angle of climb
The rate of climb depends directly on the amount of excess POWER available and the weight of the aircraft
The lower the weight, the greater the rate of climb
The greater the power, the greater the rate of climb
The lower the drag, the greater the rate of climb
So you can achieve both Vx and Vy at the max L/D ratio since the difference between Vx and Vy is to do with excess Thrust and Power and not Lift and Drag.
