Which of the following is NOT correctly matched? (Tribes) – (Location) (1) Angamis – Nagaland (2) Birhors – Jharkhand (3) Khas – Arunachal Pradesh (4) Todas – Tamil Nadu

The correct answer is C (only 3), since Khas is the only wrongly matched pair. The core concept is Scheduled Tribes and their regional distribution under Article 342, which is a recurring Prelims theme.

• 1 (Angamis, Nagaland) is correct. Angami is one of the major Naga tribes, concentrated around Kohima.
• 2 (Birhors, Jharkhand) is correct. Birhor is a Primitive Tribal Group (PVTG) found mainly in Jharkhand, traditionally forest-dependent and nomadic.
• 3 (Khas, Arunachal Pradesh) is wrong. The Khas community is associated with Uttarakhand, Himachal Pradesh and Nepal, not Arunachal Pradesh. Do not confuse it with the Khasi tribe, which is in Meghalaya.
• 4 (Todas, Tamil Nadu) is correct. The Todas are a pastoral community of the Nilgiris, known for their buffalo-centred culture.

For Mains, this links to tribal identity, forest rights and the differing state-wise tribal profiles that shape policy design under the Fifth and Sixth Schedules.

Trap: Aspirants confuse Khas with Khasi and pick a wrong option by assuming the Northeast mapping is correct.
