Who are called the untouchables in the India society?

Ans: In the caste system, the people or groups placed at the top of the ladder called themselves upper caste and considered themselves as superior. The groups who were placed at the bottom of the ladder are regarded as unworthy and called themselves as “untouchables”. The untouchables were not allowed to eat in the same room along with the upper caste people, thinking that they would pollute that person’s food.
