Nanda Devi and Kanchenjunga will both be placed in which general physical category?

Correct answer: Himalayan peaks

The governing concept is the identification of major Himalayan relief features. Nanda Devi is a high Himalayan mountain peak in Uttarakhand, while Kanchenjunga is a very high Himalayan peak associated with the Sikkim–Nepal region. Although their exact locations and local mountain sections differ, their common physical category is Himalayan peaks. Therefore, option A is correct. Deccan soils are a soil resource of Peninsular India, not mountains; eastern coastal lagoons are shallow water bodies along the coast; and Aravalli passes are routes through a separate old mountain range in northwestern India. The question asks for the shared broad category, so their common Himalayan character is more relevant than their individual state locations.
