Solution

The correct option is C $< 100$ since the pressure is less than at ground level
At ground level, the boiling point of water at the top of a mountain is $100^{o} C$ . The boiling point of water at the top of a mountain is $< 100^{o} C$ since the pressure is less than at ground level. As the pressure decreases, the boiling point decreases.
