Which of the following pairs is NOT correctly matched? Rebellion Year

1. A

   Santhal 1855

   (a) Santhal 1855. The Santhal hul of Sidhu-Kanhu is 1855–56 in the Rajmahal-Damin-i-Koh tract. The pair is correctly matched.

2. B

   Kol 1831

   (b) Kol 1831. The Kol rebellion of Chota Nagpur is dated 1831–32. The pair holds.

3. C

   Khasi 1829

   (c) Khasi 1829. Tirot Sing’s Khasi rising against the British road through Nongkhlaw is 1829. The pair holds.

4. D

   Ahom 1815

   (d) Ahom 1815. The first Ahom anti-British rising under Gomdhar Konwar is 1828, after the Treaty of Yandabo, not 1815. That wrong year is the official key.

Summary. Official key is (d) Ahom 1815. Among the four rebellion-year pairs, Ahom–1815 is the mismatch; 1815 sits near the Anglo-Nepal War, not the Ahom revolt. Santhal 1855, Kol 1831 and Khasi 1829 stay right. Neighbouring Ahom names are Gomdhar Konwar and the 1826 Yandabo treaty.
