Correct answer: (a) Kanganahalli
Explanation
- A
Kanganahalli
(a) Kanganahalli. At Kanaganahalli (Sannati, Kalaburagi, Karnataka) a limestone portrait of a king is labelled ‘Ranyo Ashoka’ — King Ashoka — on a sculpted slab from the Mahastupa. That inscribed portrait is the official key.
- B
Sanchi
(b) Sanchi. Sanchi has Ashokan pillars and stupas but not this labelled stone portrait reading Ranyo Ashoka, so it is not the key.
- C
Shahbazgarhi
(c) Shahbazgarhi. This is a major set of Ashokan Major Rock Edicts in Kharoshthi in present-day Khyber Pakhtunkhwa, without that named portrait, so it is not the key.
- D
Sohgaura
(d) Sohgaura. A Mauryan storehouse plaque, not an Ashoka portrait inscription, so it is not the key.
Summary. Official key is (a) Kanganahalli. The Sannati–Kanaganahalli stupa yielded a labelled royal portrait ‘Ranyo Ashoka’, a rare named image of the emperor. Sanchi and Shahbazgarhi are Ashokan in other ways; Sohgaura is unrelated to that portrait. Honour the stored letter (a).
