B. a dry lubricant

Explanation:

Friction is a phenomenon which resists motion when an object is rubbed against another. So friction has instances where it is desired and instances where it is not desired. When friction is not desired, we tend to reduce it. Using lubrication is one way to reduce friction. Lubricant is an substance that will occupy the space between two moving parts, so that the parts don't rub against each other with heavy friction. So the movement is much smoother and easier in the presence of lubrication. In a carrom board, we use a dry lubricant like talcum powder to reduce friction.

Option B is the answer.
