Correct answer: (b) Kunchikal fall
Explanation
- A
Jog fall
(a) Jog fall. Jog (Gersoppa) on the Sharavathi in Karnataka is a famous segmented fall of about 253 m, not India’s highest on this paper.
- B
Kunchikal fall
(b) Kunchikal fall. Kunchikal on the Varahi in Shimoga/Udupi country, Karnataka, is listed as India’s highest waterfall (about 455 m). That stored name is the official key.
- C
Rakim Kund fall
(c) Rakim Kund fall. Rakim Kund / Khandadhar-side names in the Odisha highlands are high cascades, not the keyed national maximum here.
- D
Kevti fall
(d) Kevti fall. Kevti in Rewa, Madhya Pradesh, on a Tons tributary, is a notable fall, far below Kunchikal’s listed drop.
Summary. Official key is (b) Kunchikal fall. Among the four, Kunchikal is the stored highest Indian waterfall. Jog is the celebrity Sharavathi fall, not the height key. Rakim Kund and Kevti are regional names. Neighbouring comparisons are Nohkalikai (Meghalaya) and Barehipani (Odisha), which this option set does not use.
