Pick out the wrong statement about a streamline.
(A) It is always parallel to the main direction of the fluid flow
(B) It is a line across which there is no flow and it is equivalent to a rigid
boundary
(C) Streamlines intersect at isolated point of zero velocity and infinite
velocity
(D) The fluid lying between any two streamlines can be considered to be in
isolation and the streamline spacing varies inversely as the velocity
