Explanation

(c)
According to Le-Chatelier’s principle when a system at equilibrium is subjected to change in pressure, temperature or concentration then the equilibrium is disturbed and shifts in a direction where the effect of change is annuled.
$Ice \rightleftharpoons water$
When pressure is increased in this system, the melting point of ice is decreased $i.e$., more ice melts and more water is formed.
