Concept:
Tribal societies in India possess traditional systems of governance in which village leadership plays an important role in:
• Social administration,
• Maintenance of customary law,
• Settlement of disputes,
• Preservation of moral order.
Different tribes use different titles for their traditional leaders.
Step 1: Understanding the term “Manjhi”.
The title:
\[
Manjhi
\]
is associated with the traditional village headman among the:
\[
\boxed{\text{Santhals}}
\]
The Manjhi acts as:
• Administrative head,
• Judicial authority,
• Moral guide,
• Custodian of customs and traditions.
Thus, the Manjhi possesses both:
• Civil authority,
• Moral authority.
Step 2: Analyzing Option (A) — Gujars.
Gujars are mainly:
• Pastoral communities,
• Traditionally cattle-herding groups.
Their village leadership structure is not centered around the title “Manjhi.”
Hence:
\[
\text{Option (A) is incorrect.}
\]
Step 3: Analyzing Option (B) — Bakarwals.
Bakarwals are:
• Nomadic pastoralists,
• Primarily found in Jammu and Kashmir.
Their leadership traditions do not use the title “Manjhi.”
Therefore:
\[
\text{Option (B) is incorrect.}
\]
Step 4: Analyzing Option (D) — Nagas.
Naga tribes possess their own systems of village councils and chieftainship.
However:
\[
\text{“Manjhi” is not a Naga title.}
\]
Thus:
\[
\text{Option (D) is incorrect.}
\]
Step 5: Final conclusion.
Therefore, the village headman known as “Manjhi” belongs to the:
\[
\boxed{\text{Santhal tribe}}
\]
Hence, the correct answer is:
\[
\boxed{\text{(C) Santhals}}
\]
