The correct answer is 'maximum at the inside of the surface'.
In a viscous fluid flowing through a circular pipe, the shear stress is zero at the centre of the pipe and increases linearly with radial distance, reaching its maximum value at the pipe wall (the inside surface of the pipe).

The answer is Maximum at the pipe surface because the pipe surface will the zone of 'no slip area' where the nearest layer of the liquid is expiring the highest shear force and it moves very slowly as compared to the mean layer of water so that the maximum shear force will more near to pipe surface.

The option B is correct.
As per my knowledge, shear stress is linearly increased from the centre (r=0) and maximum at boundary where (r max).

I think the given answer is correct because it is being asked regarding Shear stress distribution in VISCOUS FLUID.
So, for VISCOUS FLUID shear stress distribution will be the same throughout the section.

In the case of inviscous flow i.e. ideal flow shear stress distribution is of rectangular shape so answer c is correct.
In case of real flow steady and laminar then option B will be correct.
In case of real flow steady and laminar then option B will be correct.
