Correct Option: B

Lucius Flavius Arrianus ‘Xenophon’, known in English as Arrian, and Arrian of Nicomedia, was a Greek historian, a public servant, a military commander and a philosopher of the Roman period. Indica is also the name of a similar book by Megasthenes that also describes the history of India and was a major source from which Arrian drew. Megasthenes (ca. 350 – 290 BCE) was a Greek ethnographer and explorer in the Hellenistic period, author of the work Indica. He was born in Asia Minor (modern day Turkey) and became an ambassador of Seleucus I of the Seleucid dynasty possibly to Chandragupta Maurya in Pataliputra, India. However the exact date of his embassy is uncertain. Scholars place it before 298 BC, the date of Chandragupta’s death.
