Answer:
A. Gas
Explanation:
The physical state, or phase, is a way that the molecules are distributed at a space. The phase depends on the molar mass of the compound, on the internal forces of it, and the temperature and the pressure.
As high is the molar mass, as difficult is to the compound be "free" in a gas phase because it's too "heavy". As strong is the internal forces, as difficult is for the compound to have more internal distances, its components intended to be together.
As higher is the temperature and the pressure, the internal energy of the compound intends to increase, their components have higher velocities, and because of that, they intend to be more separated. So, it's most likely to it to be at a gas phase.
But the other phase can be presented in higher temperatures and pressures, all the criteria must be analyzed.
