The correct answer is option 'C' - Hoe.

The hoe is an agricultural implement that is used for removing weeds and for loosening soil. It is a simple tool that has been used for centuries by farmers and gardeners around the world. The hoe consists of a long handle with a flat blade attached to the end. The blade can be made of metal, wood, or even stone, depending on the region and the availability of materials.

The hoe is primarily used for weeding, which involves removing unwanted plants from the soil. Weeds can compete with crops for water, nutrients, and sunlight, so it is important to remove them to ensure healthy plant growth. The blade of the hoe is used to cut through the soil and sever the weeds from their roots. By removing the weeds, the hoe helps to reduce competition and improve crop yield.

In addition to weeding, the hoe is also used for loosening the soil. Soil can become compacted over time, especially in areas with heavy foot traffic or machinery. Compacted soil can hinder root growth and water absorption, so it is important to loosen it. The hoe is used to break up the soil and create small air pockets, allowing for better aeration and drainage. This helps to improve the overall health of the soil and promote plant growth.

The hoe is a versatile tool that is used in both small-scale gardening and large-scale agriculture. It is lightweight, easy to use, and requires little maintenance. It can be used in various soil types and is effective for both shallow and deep cultivation. The hoe is an essential tool for any gardener or farmer who wants to maintain weed-free and healthy soil for their crops.
