Best answer
Correct choice is (c) Cornice

The best explanation: Cornice is generally moulded and given an ornamental treatment. It is weathered and throated to dispose off rain water. In order to prevent the overturning of the cornice, sufficient bearing and extra weight at the top in the form of a parapet wall should be provided.
