An $$L$$-shaped object, made of thin rods of uniform mass density, is suspended with a string as shown in figure. If $$AB = BC$$, and the angle made by $$AB$$ with downward vertical is $$\theta$$, then:

A

$$\tan\theta = \frac{2}{\sqrt{3}}$$

B

$$\tan\theta = \frac{1}{3}$$

C

$$\tan\theta = \frac{1}{2}$$

D

$$\tan\theta = \frac{1}{2\sqrt{3}}$$
