In the context of the cultural history of India:

Option 1, `Shramana`, refers to a wandering monk. While these monks aimed to achieve the spiritual state of peace, their primary duty did not include the memorizing of chronicles or histories.

Option 2, `Parivraajaka`, is another term synonymous with wandering religious mendicants. Their primary goal was to attain spiritual enlightenment and they did not typically memorize chronicles, dynastic histories and Epictales.

Option 3, `Agrahaarika`, refers to individuals who were given grants of land or villages by the rulers of the day to maintain temples. They also wouldn`t traditionally have been entrusted with memorizing chronicles, dynastic histories, and Epic tales.

Option 4, `Maagadha`, describes singers and narrators who used to sing praises of their patrons and tell stories of their valor. Their profession involved memorizing and narrating chronicles, dynastic histories, and Epic tales, and therefore, they are the correct answer to the question.
