Near the wall, there will be no slip condition so that v=0 at the surface. D this parabolic curve is showing velocity distribution, and as per this velocity is maximum at the center.
Answer is D.
Answer is D.

Answer is correct because it is said ""near the wall"" not ""at the wall"".
Yes, at the wall, velocity will be zero but near the wall, velocity will be minimum.
Yes, at the wall, velocity will be zero but near the wall, velocity will be minimum.

The fluid velocity in a pipe changes from zero at the surface because of the no-slip condition to a maximum at the pipe center.

Fluid Velocity in a pipe is maximum at the centre, zero at the wall and minimum near the wall. So option A is absolutely right.
