Question

Select One Correct Option from the following: The moment of inertia of a thin square plateABCD, of uniform thickness about an axis passing through the centre O and perpendicular tothe plane of the plate is(where $I_{1},I_{2},I_{3} and I_{4}$ are respectively moment of inertia about axes 1,2, 3 and 4 which are in the plane of the plate.)
(A)$I_{1} +I_{2}$
(B)$I_{3} +I_{4}$
(C)$I_{1} +I_{3}$
(D)$I_{1} +I_{3}$

Answer 1

b option is correct I think
