I think in thin cylindrical shells the (radial stress is) & (longitudinal stress). So, the diameter must increase and length should decrease.

It is an option (b).

Answer is correct both length and diameter increases as pressure is acting uniform in all direction. It is not an axial force to increase the length and decrease diameter.
