Correct answer: (b) Vasupujya - Sammedashikhar
Explanation
- A
Rishabhanath - Ashtapad
Rishabhanath (Adinatha), the first Tirthankara, is traditionally associated with nirvana at Ashtapad (Kailasa). This pair is treated as correctly matched, so it is not the ‘NOT matched’ key.
- B
Vasupujya - Sammedashikhar
Vasupujya, the twelfth Tirthankara, attained nirvana at Champapuri (Champanagar, Bhagalpur region), not at Sammed Shikhar. Sammed Shikhar is the nirvana place of twenty Tirthankaras, not of Vasupujya. This wrong pair is the official key.
- C
Neminath - Urjayanta
Neminath (Arishtanemi) is associated with Urjayanta—Mount Girnar in Gujarat. The pair is correctly matched.
- D
Mahavira - Pavapuri
Mahavira attained nirvana at Pavapuri in present-day Bihar. The pair is correctly matched.
Summary. Official key is (b) Vasupujya–Sammedashikhar, the incorrectly matched pair. Champapuri is Vasupujya’s nirvana site; Sammed Shikhar (Parasnath hill, Jharkhand) is the great kalyanaka landscape for twenty Tirthankaras. Rishabha–Ashtapad, Nemi–Girnar and Mahavira–Pavapuri stand. Honour the stored letter (b).
