Given :
Assertion
Frictional heat generated by the moving ski is the chief factor which promotes sliding in skiing while waxing the ski makes skiing more easy.
Reason
Due to friction, energy dissipates in the form of heat. As a result, it melts the snow below it. Wax is water repellent.

Solution
Due to friction, energy dissipates in the form of heat. As a result, it melts the snow below it. Wax is water repellent. However this reduces some friction and makes it easier to slide
The Correct Opt = A
