Feature 1: Rabi crops are sown in winter (October to December) and harvested in summer (April to June). Important rabi crops include wheat, barley, peas, gram and mustard.
Feature 2: These crops depend on precipitation during winter months caused by western temperate cyclones, which provides the necessary moisture for their growth.

The examiner expects two distinct, clearly stated features — typically the sowing/harvesting period and the climatic/moisture requirement (western temperate cyclones). You may alternatively mention the important states (Punjab, Haryana, UP, etc.) as a second feature. Each feature should be one clear sentence. Avoid writing vague points like "they grow in winter" without mentioning the specific months, as that loses marks.
