Text Solution
Verified by ExpertsThe correct answer is:
D
According to principle of continuity, for a streamline flow of fluid through a tube of nonuniform cross-section the rate of flow of fluid 
is same at every point in the tube.
i.e,, 
constant
or 
Therefore, the rate of flow of fluid is same at M and N.
