Animal husbandry provides a source of livelihood for:

Small and marginal farmers
Landless laborers
Women
All of the above

The correct answer is: d) All of the above

Animal husbandry is the care, breeding, and use of animals, especially domestic ones. It is a major source of livelihood for small and marginal farmers, landless laborers, and women.

Small and marginal farmers are those who own or operate small farms. They often lack the resources to invest in large-scale agriculture, and animal husbandry can provide them with a way to generate income and improve their livelihoods.

Landless laborers are those who do not own land and must work for others to earn a living. Animal husbandry can provide them with a way to generate income and improve their livelihoods, as well as provide them with a source of food and nutrition.

Women are often involved in animal husbandry, particularly in developing countries. They may be responsible for caring for the animals, milking them, and selling their products. Animal husbandry can provide women with a way to generate income and improve their livelihoods, as well as provide them with a source of food and nutrition.

In addition to providing a source of livelihood, animal husbandry can also help to improve food security, reduce poverty, and protect the environment.
