as discussed in

Paraller Axis Theorem -

$I_{b\: b'}=I_{a\: a'}+mR^{2}$

- wherein

$b\: b'$ is axis parallel to $a\: a'$ & $a\: a'$ an axis passing through centre of mass.

According to parallel axis theorem,

$I=I_{c}+MR^{2}$

R is maximum for point B, so Imax is about B.

Option 1)

Option 2)

C

This option is incorrect.

Option 3)

D

This option is incorrect.

Option 4)

A

This option is incorrect.
