The melting point of most of the solid substances increases with an increase in pressure. However ice melts at a temperature lower than its usual melting points when pressure is increased. This is because:

Athe density of ice is lesser than $$H_{2}O$$
Correct Answer
Bpressure generates heats
Cthe chemical bonds break under pressure
Dice is not a true solid

Solution

This can be explained with the help of Le Chatelier's principle.
As the density of ice is lesser and has more volume than water while applying pressure the volume decreases due to which its equilibrium is subjected to change and to counteract the effect of the change, it converts into liquid (water).
