If $$\cos(A - B) = \frac{\sqrt{3}}{2}$$ and $$\cos(A + B) = 0$$, where A and B are positive acute angles and A $$\geq$$ B, then the measures of A and B are:

A

$$80^{\circ}$$ and $$10^{\circ}$$

B

$$60^{\circ}$$ and $$30^{\circ}$$

C

$$70^{\circ}$$ and $$20^{\circ}$$

D

$$50^{\circ}$$ and $$40^{\circ}$$
