I think Both B and C are correct.

Option C is correct because in the case of an RCC prismatic beam neutral plane lies below C.G. (in the case of cantilever RCC beam, above CG).

No compression no tension so does not change during deformation. C is correct.

Option A is the correct answer.

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.

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.

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

Yes B also the answer.
