Detailed Explanation:

Answer: Option 1 — 1 only

This question tests the correct matching of cultural traditions with their associated communities. Only the first pair is correctly matched, as Chaliha Sahib is indeed a Sindhi Hindu festival, while the other two pairs incorrectly associate traditions with communities.

✅ Pair 1 – Correct: Chaliha Sahib (also called Chalio or Chaliho) is a forty-day-long festival celebrated by the Hindu Sindhi community, observed in honor of Jhulelal (Uderolal), the patron saint of Sindhis.

❌ Pair 2 – Incorrect: Nanda Raj Jaat Yatra is a pilgrimage festival associated with the people of Uttarakhand (particularly the Garhwal region), not the Gond community, which is an indigenous tribe of central India.

❌ Pair 3 – Incorrect: Wari-Warkari is a pilgrimage tradition associated with devotees of Lord Vitthal (Vithoba) in Maharashtra, primarily involving the Marathi-speaking community, not the Santhals, who are an indigenous tribe of eastern India.
