Correct option is D
The correct answer is: (d) Chandragupta Maurya
Megasthenes, a Greek historian and ambassador, visited Pataliputra (modern-day Patna) during the reign of Chandragupta Maurya (321–297 BCE). He was sent by Seleucus I Nicator, the ruler of the Seleucid Empire, to the Mauryan court as part of a diplomatic relationship between the two empires.
Key Contributions of Megasthenes:
Indica:
- Megasthenes wrote Indica, a detailed account of India’s society, administration, and geography during the Mauryan period.
- Though the original text is lost, its content survives through references in later works by Greek and Roman historians.
Description of Pataliputra:
- He described Pataliputra as a well-planned city with wooden walls, a large moat, and watchtowers, reflecting the advanced urban planning and administration under Chandragupta Maurya.
Observation of Society and Governance:
- Documented the caste system, the absence of slavery, and the prosperity of the Mauryan Empire.
- Described Chandragupta Maurya's court and the administrative efficiency of the empire.
Additional Information:
- Chandragupta I: Founder of the Gupta Empire, ruled much later (circa 4th century CE).
- Harshvardhan: Ruled in the 7th century CE, long after Megasthenes’ time.
- Chandragupta II: A Gupta emperor (4th–5th century CE), also known as Chandragupta Vikramaditya, unrelated to Megasthenes.
