Rabi is also known as:

Rabi crops are distinct from Kharif crops as they are sown in the winter months, typically from October to November, and harvested as the weather warms up in spring. Due to this specific harvesting period, which generally occurs between April and May, Rabi crops are commonly referred to as the Spring harvest. This term, making option C correct, accurately reflects the season of their collection. Options A ('Summer and Autumn harvest'), B ('Spring and Summer harvest'), and D ('Summer harvest') are incorrect because they include seasons not associated with the primary harvesting period of Rabi crops, which are distinctly linked to the cooler months and spring.
