Concept:
Foreign travelers are extremely important sources for reconstructing ancient Indian history. Their writings provide valuable details regarding:
• administration,
• social customs,
• religion,
• economy,
• and political conditions.
To solve chronological order questions, we must determine the approximate historical period in which each traveler visited India.
Step 1: Identifying the earliest traveler among the given names.
\[
\text{Niyarkes (Nearchus)}
\]
Niyarkes was a Greek naval commander associated with Alexander the Great.
He visited northwestern India around:
\[
326 \text{ BCE}
\]
Thus, he is the earliest among the given travelers.
Therefore:
\[
C = \text{First position}
\]
Step 2: Determining the next traveler chronologically.
\[
\text{Megasthenese}
\]
Megasthenes came to India as an ambassador of Seleucus Nikator in the court of Chandragupta Maurya.
He visited India around:
\[
4^{th}\text{ century BCE}
\]
He wrote the famous work:
\[
\textit{Indica}
\]
Thus:
\[
B = \text{Second position}
\]
Step 3: Finding the next traveler in sequence.
\[
\text{Daimachos}
\]
Daimachos came after Megasthenes and served as an ambassador in the Mauryan court during the reign of Bindusara.
Thus:
\[
D = \text{Third position}
\]
Step 4: Identifying the latest traveler.
\[
\text{Fa-hien}
\]
Fa-hien was a Chinese Buddhist pilgrim who visited India during the Gupta period in the reign of Chandragupta II.
He visited India during:
\[
5^{th}\text{ century CE}
\]
Thus:
\[
A = \text{Fourth position}
\]
Step 5: Writing the complete chronological sequence.
Hence, the correct chronological order is:
\[
\boxed{C \rightarrow B \rightarrow D \rightarrow A}
\]
Therefore, the correct option is:
\[
\boxed{(3)\ C, B, D \text{ and } A}
\]
Step 6: Historical significance of foreign travelers.
The accounts of these travelers help historians understand:
• Mauryan administration,
• Gupta society,
• Buddhism in India,
• trade routes,
• and urban development.
Their writings serve as external evidence for Indian history.
