The correct answer is: c) Extensive farming.

Extensive farming methods include grazing livestock on open range, growing crops on large fields, and harvesting timber from forests.
Intensive farming is a type of agriculture that uses a small amount of land to produce a large amount of food. It is often used in areas where land is scarce and labor is available. Intensive farming methods include raising livestock in confined spaces, growing crops in greenhouses, and using high-yield varieties of crops.
Semi-intensive farming is a type of agriculture that combines elements of both extensive and intensive farming. It is often used in areas where land is not as abundant as labor. Semi-intensive farming methods include raising livestock in open pastures and growing crops in fields with irrigation.
Commercial farming is a type of agriculture that is carried out for profit. It is often used in areas where there is a large market for agricultural products. Commercial farming methods include using modern technology, applying large amounts of fertilizer and pesticides, and raising livestock in large-scale operations.
In Tamil Nadu, the majority of livestock farmers practice extensive farming. This is because Tamil Nadu has a large amount of land that is suitable for grazing livestock. Additionally, labor is relatively scarce in Tamil Nadu, which makes extensive farming a more cost-effective option.
