Answer: B) remain same

If a substance is at its triple point and we increase the pressure, then the triple point will remain the same.

A triple point is a condition in which a substance exists in a state of equilibrium between three phases, typically solid, liquid, and gas. The triple point is a unique point on a phase diagram that represents the temperature and pressure at which all three phases of the substance can coexist in equilibrium.

If the pressure is increased at the triple point, the temperature will remain the same because it is the temperature at which all three phases of the substance can coexist. The triple point will remain the same because it is a unique point on a phase diagram and is independent of external conditions such as pressure.

Therefore, the correct answer is b) remain the same.

c) decrease

When the substance is at its triple point, it means that the solid, liquid, and gas phases coexist in equilibrium. If you increase the pressure at the triple point, the equilibrium between the phases will be disturbed, and the temperature at which all three phases coexist will decrease.
