(A) is wrong. Dissociation of water is an endothermic reaction, so increasing T will increase [ H ⊕] and hence decrease in pH (R) is correct

Q. Statement 1 : $p H$ of water increases with an increase in temperature
Statement 2 : $K_{w}$ or water increases with increase in temperature

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
