What about "b"?

Answer B is also correct.
Subhankar said:

Yes B also the answer.

At neutral axes, there is no compression &tension. So during deformation, the neutral plane does not change. So option c is correct.

C is correct because C.G can change especially when we are dealing with cracked section of concrete. The code always assumes the same Neutral Axis or Neutral plane even if it is cracked section.

I think Option B is correct.

The neutral axis passes through the center of forces while the center of gravity is the center of masses. So, B may not be always true. Ex: RCC beam design. But in regular str it coincides.
