Match List-I with List-II and select the correct answer from the codes given below the lists: List-I (Tribes) A) Khirghiz B) Bushman C) Ainu D) Badduin List-II (Area) 1) Japan 2) Arab 3) Central Asia 4) Kalahari

The correct answer is C. The matches are Khirghiz with Central Asia (3), Bushman with Kalahari (4), Ainu with Japan (1) and Badduin with Arab (2).

• Khirghiz (Kyrgyz): a Turkic pastoral people of the Tian Shan and Pamir region, now the core population of Kyrgyzstan in Central Asia.
• Bushman (San): hunter-gatherers of the Kalahari Desert spanning Botswana, Namibia and South Africa, in southern Africa.
• Ainu: the indigenous people of Hokkaido and the northern islands of Japan. Japan's Diet recognised them as indigenous in 2008, and the Ainu Promotion Act of 2019 followed.
• Badduin (Bedouin): nomadic Arab pastoralists of the Arabian and Syrian deserts.

Option A wrongly places the Khirghiz in Japan and the Ainu in Central Asia. Option B places the Bushman in Central Asia, which is a clear mismatch since the Kalahari is in Africa. Option D places the Bedouin in Japan, which has no basis.

The core concept is the ethnographic distribution of tribes and the link between a tribe's livelihood and its environment: desert pastoralism, forest-hunting, and steppe nomadism. This ties to the Prelims geography and culture segment and to Mains questions on indigenous communities and their rights.

Trap: aspirants often anchor on one pair they know well, such as Ainu with Japan, and then pick the option that fits that pair without checking the other three.
