Final answer:
Option C, H, q, V, includes only state functions in Chemistry. Examples of state functions include enthalpy (H), entropy (S), and volume (V).
Step-by-step explanation:
The group that includes only state functions is option C. H, q, V. State functions are properties that depend only on the current state of the system and not on the path by which the system arrived at that state.
Examples of state functions include enthalpy (H), entropy (S), and volume (V).
