(c) I, II and IV
Statements I and II are correct — Rabi crops are sown in winter (October–December) and harvested from April to June. Statement IV is correct — Punjab, Haryana, and Uttar Pradesh are important for wheat. Statement III is wrong as Maize, Cotton, and Jute are Kharif crops, not Rabi.

The key is to identify the incorrect statement. The passage clearly lists Rabi crops as wheat, barley, peas, gram, and mustard — not maize, cotton, or jute (those are Kharif crops). Statements I and II match the passage exactly. Statement IV is mostly correct (Punjab, Haryana, UP are mentioned). Eliminating Statement III points directly to option (c).
