Which of the following, based on the kinetic-molecular theory of gases, best explains Avogadro's law?

• A. Avogadro's law is valid independent of the chemical identity of the gas since the volume of space occupied by gas molecules is significantly less than the volume of space between molecules.
• B. Avogadro's law is valid dependent on the chemical identity of the gas since gas molecules are always moving quickly and randomly.
• C. Avogadro's law is valid independent of the chemical identity of the gas since gas molecules do not have attractive or repulsive forces with each other.
• D. Avogadro's law is valid dependent on the chemical identity of the gas since the temperature of the gas affects the average kinetic energy of the gas molecules.
