The correct option is A Agriculture
Agriculture is the practice of cultivating useful plants and animals. Early humans led a nomadic life, that means they used to travel from place to place in search of resources like food, water etc.
Over years of evolution, early humans started agriculture. This changed the wanderer lifestyle (nomadic) of the human population into a sedentary lifestyle in the neolithic age.
They were able to do crop cultivation and cattle raising which gave them food security. They started rearing animals like sheeps, cows, etc. for milk, meat and clothes too. They also did fishing for food.
Animal husbandry is the systematic rearing, caring and breeding of livestock. Livestock constitutes domestic animals kept for use or profit like cows, pigs, sheep, camels etc.
Cattle is a generalised term used for the large domesticated hoofed animals. Examples include cow, buffalo, ox, etc.
Breed is a specific group of animal or plant exhibiting homogenous characters in appearance and behaviour which are distinct from other organisms of the same species. Example is the Jersey cow.
