Extensive property:

• A property of a system, where magnitude depends upon the amount of matter is known as extensive property. 

Properties like:

• Mass, volume, internal energy, heat content, free energy, enthalpy, entropy, heat capacity, surface area, energy etc. are dependent upon the mass of the system and are called extensive properties. 

Intensive property:

• A property of a system, whose magnitude does not depend upon the amount of matter, is known as intensive property. 

Properties like:

• Temperature, pressure, surface tension, viscosity, specific heat, molar energy, molar entropy, density, refractive index etc. are independent of the mass of the system and are called intensive properties. 

Hence, the correct option is (A).
