Solution

The correct option is B The point where the temperature and pressure conditions are right for all three states, solid, liquid and gas, to exist together at equilibrium.
The triple point is the point where the temperature and pressure conditions are right for all three states, solid, liquid and gas, to exist together at equilibrium.

Hence, the correct option is A.
