One historical reason that people in the indian subcontinent have been reluctant to use livestock for food has been that a. their digestive systems are unable to handle meat and proteins b. they refused to eat meat in order to show resistance to british imperialism c. they are able to use cattle as a labor mainstay of their agriculture d. they can use the meat from cattle as fertilizer to make crops grow better

The correct answer is - They are able to use cattle as a labor mainstay of their agriculture.

One of the first animals that got domesticated on the Indian subcontinent has been the cattle. The cattle was actually used for labor, not as a food source itself. The reason for that was that the Indian subcontinent provided lot of food sources, especially from the agriculture, so there was no need for the cattle to be consumed as well. Plus, the cattle was the best labor force they had, so there wasn't any sense to kill it since it is helping to provide much more food with its labor than what it can offer if consumed.

That has remained as a tradition in this region, and over time even got a religious dimension, so even nowadays, the cattle is not killed and eaten.
