Z1 is not equal to z2 in this case.
So the answer is 'c'.
So the answer is 'c'.

Opt-c is correct as sudden enlargement of pipe, so change in momentum is also taken into acc.

Bernaullie's principle: As with having different areas of flow of a fluid through a convergent pipe,give us a reason to apply conservation of energy equation having relation with pressure,velocity and density of the respective fluid.
As for a pipe having two ends with different dimensions of respectively pressure,velocity and densities then we have the equation as-{(p1/wg+v1square/2g+z1)-(p2/wg+v2square/2g+z2)}=constant.
