If you are reading the traveller's accounts, which of the following would be of Al-Biruni:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Explanation of the caste system by looking for parallels in ancient Persia.
Al-Biruni, who came to India in the 11th century, tried to understand Indian society and explained the caste system by looking for parallels in ancient Persia.
" Al-Biruni tried to explain the caste system by looking for parallels in other societies. He noted that in ancient Persia, four social categories were recognised: those of knights and princes; monks, fire-priests and lawyers; physicians, astronomers and other scientists; and finally, peasants and artisans. In other words, he attempted to suggest that social divisions were not unique to India. At the same time he pointed out that within Islam all men were considered equal, differing only in their observance of piety."
