Statement I: Work is a path function. True. Work depends on the path taken between initial and final states, not just on the states themselves. Hence, work is a path function. Statement II: Enthalpy is an extensive property. True. Enthalpy (H) depends on the amount of substance. If the system size doubles, enthalpy doubles. So it is an extensive property. Statement III: Lattice enthalpy of ionic compounds can be obtained from BornHaber cycle. True. The Born-Haber cycle uses Hess's law to calculate lattice enthalpy indirectly from measurable thermodynamic quantities. Correct statements: II and III are correct, and actually, I is also correct. Wait, let's double-check statement I : Work is NOT a state function (true), but it is a path function - the statement says "Work is a path function" - That is correct. Therefore all three I, II, and III are correct. Final Answer: Option D - I, II and III
