B) The triple point is higher than room temperature.
C) The triple point is equal to room temperature.

Question

The triple point is the temperature and pressure at which all three phases (solid, liquid, and gas) coexist. Since naphthalene sublimes at room temperature, it means that at room temperature, the solid phase transitions directly to the gas phase without passing through the liquid phase. Therefore, the triple point must be at a higher temperature where the liquid phase can exist.
