Consider the modes of transformations of a gas form state `A` to state `B` as shown in the given `P-V` diagram. Which one of the following is true?

Options

A. `DeltaH = q` along `A rarrC`.
B. `Delta S` is same along both `A rarrB` and `A rarr C rarrB`
C. `w` is same along both `A rarrB` and `A rarr C rarrB`
D. `w gt 0` along both `A rarr B` and `A rarrC`

Explanation

Work `(w)` is a state function. It depends upon the initial and final state of system.
