I agree @Sumith.

Both (B & D) are correct. A good quality cement should settle down when dropped in water & it should not float on surface.

Which put in a hand the cement should feel cool. Why because cement chemical reaction started it get hard. In this process gives a lot of heat due to chemical action.
