Answer:
The correct answer is C) The people were born into social classes and remained there all their lives.
Explanation:
The Aryan's in the Indus River Valley had a ridged Caste System based on old beliefs. People were born into different social classes, called a caste. The highest caste were the Priests and the learned men while the lowest caste were the 'untouchables'
It was thought that the caste you are born was is based on how good or bad that person was in their previous life.
If the person was a sinner, they would be born into the lower castes, while if the person was a good in their previous life, they will be reincarnated into the higher castes.
Hence, moving from one caste to another was impossible and people.
