large moment of inertia with less cross-sectional area
large moment of resistance as compared to other section
greater lateral stability
all the above.

Yes, Of course there is no doubt that the I-section is the suitable one, Among all other, So, the Answer is D. All of the above.

I-Section is preferred to the rectangular section for resisting Bending Moment (BM) because in I-Section more than 80% of the bending moment is resisted by the flanges itself! I-Section has a higher moment of resistance (MoR) because the areas of flanges is away from the neutral axis (N.A).

What happens when the moment of inertia is more?

Can anyone explain?
