Concept:
Numismatics refers to the study of coins and currency. In ancient Indian history, coins are extremely important historical sources because they provide information regarding:
• kings and dynasties,
• political authority,
• trade and economy,
• religious symbols,
• and chronology.
For the Indo-Greeks, coins are among the most reliable historical sources.
Step 1: Understanding Assertion (A).
Assertion (A) states:
\[
\text{Numismatic evidence is an important source for the political history of Indo-Greeks.}
\]
This statement is correct.
The Indo-Greek rulers left behind a large number of coins containing:
• names of kings,
• portraits,
• titles,
• and religious symbols.
These coins help historians reconstruct the political history of the Indo-Greeks.
Step 2: Understanding Reason (R).
Reason (R) states:
\[
\text{Many Indo-Greek Kings are known only from their coins.}
\]
This statement is also correct.
In many cases:
• literary records are absent,
• inscriptions are limited,
• but coins survive in large numbers.
Thus, historians know several Indo-Greek rulers primarily through numismatic evidence.
Step 3: Evaluating the relationship between Assertion and Reason.
The Reason directly explains the Assertion because:
• numismatic evidence becomes important precisely because coins are the primary evidence available.
Therefore:
• Assertion (A) is correct,
• Reason (R) is correct,
• and Reason (R) correctly explains Assertion (A).
Step 4: Historical significance of Indo-Greek coins.
Indo-Greek coins are historically valuable because they reveal:
• Greek artistic influence,
• bilingual inscriptions,
• religious syncretism,
• and trade connections.
Coins of rulers such as Menander are especially important historical sources.
Step 5: Final conclusion.
Both statements are correct, and the Reason correctly explains the Assertion.
Therefore, the correct answer is:
\[
\boxed{\text{Both (A) and (R) are correct and (R) is the correct explanation of (A)}}
\]
