Assertion (A): Property tables list different values of some properties for a substance at the same state as a result of using different reference states.
Reason (R): The reference state chosen is of no consequence in thermodynamic process calculations as long as we use values from the single consistent set of tables.
a) Both A and R are individually true and R is the correct explanation of A
b) Both A and R are individually true but R is not the correct explanation of A
c) A is true but R is false
d) A is false but R is true
