The correct option is (c).
Explanation
Agricultural practices involve the use of specific implements for different stages of crop production, such as soil preparation, sowing, and harvesting. The sickle is a traditional hand tool predominantly used during the harvesting phase.- Statement 1 is Incorrect: Ploughing or tilling is the process of loosening and turning the soil to prepare it for sowing. This task is performed using tools such as a plough, hoe, or cultivator. A sickle is not designed for soil preparation.
- Statement 2 is Correct: The sickle is extensively used for manual harvesting. It allows farmers to cut cereal crops (like wheat and rice) and grass for fodder close to the ground.
- Statement 3 is Correct: Structurally, a sickle consists of a sharp, curved metal blade attached to a handle (usually wooden). The inner curve of the blade is sharp, enabling the user to gather crop stalks and cut them with a drawing motion.
Key Takeaway: A plough is used for tilling the soil, whereas a sickle is a curved hand tool used specifically for harvesting crops.
