Question: According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through centre of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)
[A].

IP = IG + Ah2

[B].

IP = IG – Ah2

[C].

IP = IG / Ah2

[D].

IP = Ah2 / IG
