Its simple logic. When we blow air into balloon, its whole (3D) dimension will increase. Because the pressure inside it is uniformly distributed over its entire internal area.
Same concept is here. Here the internal pressure is not uniaxial in which longitudinal dimension will increase and lateral will decrease. It is of 3 dimensional. So given answer is correct.

When a thin shell is subjected to an internal pressure. Hoop stress developed is tensile therefore increase in dia also. Longitudinal stress developed is a tensile therefore increase in length also. So the correct answer is Option D.

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.

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).
It is an option (b).

How both diameter and length increases. I think so it is not correct.
In my view diameter decreases, length increases. Could anyone support me.

Pressure depend on volume of cylinder, so both is uniformly increasing. All related data is constant. So this is correct.

Pd/4t is the formula for a thin cylindrical shell. So, p is directly proportional to d wherever d=2l.

Due to internal pressure, both d & L will increase as volume will also increase.

Pressure acting uniformly over entire inside area which tends it not to contract.

YES, In my thought of view is increase the Dia and Decrease the length.
