Solution

The correct option is B 2
1. Entropy is an extensive property. So, this statement is true.
2. This statement is false as entropy is a state function.
3. This statement is false as we know from the second law of thermodynamics that all sponteneous processes are accompanied with an increase in entropy i.e ΔSuniverse>0.
4. The given statement is true as it can be modified as
ΔSuniverse=ΔSsys+ΔSsurr

So, we can see that 2 statements are true.
