Correct answer: (a) 1 only
Explanation
- A
1 only
Arasavalli in Srikakulam district, Andhra Pradesh, has a well-known Sun temple (Suryanarayana). Amarkantak is the Narmada–Son source pilgrimage with Shiva and Narmada shrines, not a famous Sun temple. Omkareshwar is a Jyotirlinga of Shiva on the Narmada. Hence 1 only is the official key.
- B
2 and 3 only
Option (b) is 2 and 3 only. Neither Amarkantak nor Omkareshwar is famous as a Sun temple. This option is not the key.
- C
1 and 3 only
Option (c) is 1 and 3 only. Omkareshwar is Shaiva, not a Sun temple. This option is therefore wrong.
- D
1, 2 and 3
Option (d) is all three. The two Narmada sites are not Sun temples. This option is not the key.
Summary. Official key is (a) 1 only. Among the stem places, only Arasavalli is famous for a Sun temple. Amarkantak is a river-origin and Shaiva centre; Omkareshwar is a Jyotirlinga. Konark, Modhera and Martand are other classic Sun temples not listed here. Only statement 1 holds.
