Which one is not a state function?

Solution
The correct option is C Heat (q)
Internal energy volume, enthalpy, pressure, entropy are state functions, i.e. their value depends only on the initial and final state and not on the path by which that state has been derived. Whereas Heat (Q) is a path function, as its value depends upon the path followed by the process.
