Concept:
Megasthenes was a Greek ambassador sent by Seleucus Nikator to the court of Chandragupta Maurya. He wrote a book called Indica, which contains valuable information about:
• Mauryan administration,
• Indian society,
• economy,
• and social divisions.
His observations are among the most important foreign accounts of ancient India.
Step 1: Understanding Assertion (A).
Assertion (A) states:
\[
\text{Megasthenes has given a graphic account of the caste system of ancient Indian society.}
\]
This statement is correct because:
• Megasthenes described Indian society in detail,
• he explained social divisions and occupations,
• and his work provides information about the structure of ancient Indian society.
Therefore, Assertion (A) is correct.
Step 2: Understanding Reason (R).
Reason (R) states:
\[
\text{He enumerates eight classes or castes into which the whole population of India is divided.}
\]
This statement is incorrect.
Megasthenes actually described seven social divisions or classes, not eight.
These included groups such as:
• philosophers,
• farmers,
• soldiers,
• herdsmen,
• artisans,
• magistrates,
• and councillors.
Thus, the statement mentioning eight classes is wrong.
Step 3: Evaluating the relationship between Assertion and Reason.
Since:
• Assertion (A) is correct,
• but Reason (R) is incorrect,
the correct option must state:
\[
\text{(A) is correct but (R) is not correct}
\]
Step 4: Historical significance of Megasthenes’ account.
Megasthenes’ Indica is historically important because it provides:
• information about Mauryan society,
• administrative organization,
• urban life,
• and social practices.
Although some of his observations contained inaccuracies, historians still consider his account highly valuable.
Step 5: Final conclusion.
Assertion (A) is correct, but Reason (R) is incorrect because Megasthenes described seven classes, not eight.
Therefore, the correct answer is:
\[
\boxed{\text{(A) is correct but (R) is not correct}}
\]
