Extensive Variables
Extensive variables are those properties of a system that depend on the size or amount of the system. They are additive in nature and their value depends on the quantity of matter present in the system. The following are the extensive variables:
Internal energy, volume, total mass
The internal energy of a system is the sum of the kinetic and potential energies of its particles. It is an extensive variable because its value depends on the amount of matter present in the system. The greater the number of particles, the greater the internal energy.
The volume of a system is the amount of space it occupies. It is an extensive variable because its value depends on the size of the system. The greater the volume, the greater the amount of matter present in the system.
The total mass of a system is the sum of the masses of all its constituent particles. It is an extensive variable because its value depends on the amount of matter present in the system. The greater the number of particles, the greater the total mass.
Therefore, the correct answer is option C, which includes all three extensive variables.

Option C is correct
extensive property means property dependent on
amount or moles mass ,volume , internal energy are
extensive property but specific internal energy is an
intensive property........ don't confuse!
