A uniform rod of length $$\ell$$ swings from a pivot as a physical pendulum. The position of the pivot can be varied along the length of the rod. The minimum time period with which the rod can oscillate with an appropriate position of the pivot is $$T=2\pi\sqrt{\frac{L}{g}}$$ where $$L$$ is equal to

A

$$\frac{\ell}{2}$$

B

$$\frac{\ell}{\sqrt2}$$

C

$$\frac{\ell}{\sqrt3}$$

D

$$\frac{\ell}{2\sqrt3}$$
