The correct answer is: (B), (E), (A), (D), (C) Explanation & Key Takeaways: • Descending order (highest → lowest) — concise statement: • Kanchenjunga (b) > Nanga Parbat (e) > Nanda Devi (a) > Badrinath (d) > Gangotri (c). • This ordering is based on the commonly accepted summit elevations of the named peaks/peaks-of-the-group. • Kanchenjunga — overview & height: • Definition / significance: Kanchenjunga is the third-highest mountain in the world and the highest point in India (on the India–Nepal border). • Official summit elevation: 8,586 metres (28,169 ft). • Why it ranks first in this list: No other peak in the list exceeds 8,586 m, so Kanchenjunga is the tallest among the five names given. • Nanga Parbat — overview & height: • Definition / significance: Nanga Parbat is a major Himalayan “eight-thousander” noted for its huge relief and technical difficulty; commonly called the “Killer Mountain.” • Official summit elevation: 8,126 metres (26,660 ft). • Why it comes second: Its 8,126 m summit is lower than Kanchenjunga (8,586 m) but higher than Nanda Devi and the others listed here. • Nanda Devi — overview & height: • Definition / significance: Nanda Devi is the highest mountain located entirely within India (in the Garhwal Himalaya) and a prominent, historic peak for Indian mountaineering. • Official summit elevation: 7,817 metres (often reported as 7,816–7,817 m). :contentReference[oaicite:2]{index=2} • Why it sits third: Its elevation (≈7,817 m) places it below Nanga Parbat (8,126 m) and Kanchenjunga (8,586 m) but above the Badrinath and Gangotri peaks cited below. • Badrinath — clarification & height: • Important clarification: “Badrinath” is commonly known as a pilgrimage town (≈3,100 m), but there is also a named high peak in the broader region referenced in mountain literature as “Badrinath Peak.” When arranging peaks by summit height, that peak (when meant) is what is compared here. • Representative peak elevation used here: Badrinath Peak is documented at about 7,138 metres (23,420 ft) in standard reference sources (Britannica lists a Badrinath Peak ≈7,138 m). • Why it is placed fourth: The 7,138 m figure is lower than Nanda Devi (≈7,817 m) but higher than the principal Gangotri massif peaks used below (≈6,600–6,700 m), so it ranks fourth among the five items given. • Gangotri — clarification & height: • Definition / common meaning: “Gangotri” often refers to a glacier, a pilgrimage town, or the Gangotri massif. In mountaineering contexts the tallest summit in that group is Gangotri I (the Gangotri group’s main peak). • Representative summit elevation used here: Gangotri I (the main Gangotri peak) is ≈6,682 metres (21,923 ft). • Why it is last: At ≈6,682 m (or the ~6,500–6,700 m range for peaks in the Gangotri massif) it is the lowest summit among the five named items when the higher Badrinath Peak (≈7,138 m) is taken into account.
