Answer 1

Hint:
Agricultural machinery is used mainly in farming or additional agriculture. There are various kinds of gears, from hand tools and power tools to tractors and the uncountable types of farm gears that they haul or run. Assorted selections of gear are used in both organic and nonorganic farming. Particularly since the arrival of mechanised agriculture, agricultural machinery is a crucial part of how the world is fed.

Complete step by step solution:
A sickle, bagging hook or reaping-hook is a single-handed agricultural tool intended with diversely bent edges and characteristically used for harvesting, or reaping, grain crops or cutting succulent forage mainly for feeding livestock. It can be freshly cut or dried as hay. At first, Flax was used as a synonym but later it was used to mean any of a number of tools that had a curved blade. It had to be sharp on the inside edge such as a scythe. Hundreds of region-specific variants of the sickle have evolved since the start of the Iron Age. Initially, it started with iron and later steel was included in the mix. The variations in the sickle types appear in many cultures and can be divided into smooth or serrated blades. Each of these blades can be used for cutting fresh grass or mature cereals using numerous techniques.

Thus, option (B) is correct.

Note:
The inside of the blade's curve is sharp. The blade is swung or drawn towards the base of the crop. The blade catches the stem and slices it at the same time. The crop may be held in a bunch, on the other hand, held in place by a wooden stick, or left free. The movement of the sickle is opposite, being the crop is to be held by hand. Other colloquial names for basically the same tool are grass hook, swap hook, rip-hook, slash-hook, reaping hook, brushing hook or bagging hook.
