Solution

The correct option is B high temperature high pressure
Melting of ice:-
$I c e + H e a t ⇌ w a t e r$
More less volume
Volume
It is an endothermic reversible process. It involves a decrease in volume. So by Le Chatelier's principle:-
$(a)$ On increasing pressure, equilibrium shifts towards the direction of decrease in volume. So, increasing pressure favour change of ice to water.
$(b)$ Since the change of ice to water is the endothermic process, increase in temperature tends to shift the equilibrium to right. So, it favours the melting of ice.
