Solution

The correct option is B 12π3g2L
For rigid body oscillating about horizontal axis passing a point is given by
T=2πImgR where R=L/2 i.e distance of the point of pivot to the centre of gravity and I is moment of inertia.
I=1/3mL2
After putting the values of R and I we have
T=2π2L3g
Hence frequency is f=12π3g2L
