Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Velocity & Range of the distance are directly proportional to the pressure above the liquid and it is pure mechanics and given by
$v = \sqrt{2 g h} & R = 2 \sqrt{(H - h) h .}$
