The Correct Option is B

Solution and Explanation

Concept: Extensive properties depend on the amount of substance present, whereas intensive properties are independent of the amount of substance.

Step 1:
Classify the properties.
• Temperature and pressure are intensive.
• Heat capacity, enthalpy and entropy are extensive.
• Specific heat and molar heat capacity are intensive.
• Density, mole fraction and viscosity are intensive.

Step 2:
Choose the correct set. Only Option (B) contains exclusively extensive properties.

Step 3:
Final conclusion. \[ \boxed{\text{Heat capacity, Enthalpy and Entropy}} \] Hence, the correct option is \(\boxed{(B)}\).
