Which foreign traveller left a detailed account of Vijayanagara during Krishnadevaraya's reign?
Explanation
The statement is resolved by identifying Domingo Paes as the precise match. Portuguese traveller Domingo Paes described Vijayanagara's markets, festivals, fortifications and royal centre during the reign of Krishnadevaraya. Vijayanagara and the Deccan states combined agrarian revenue, fortified capitals, temple-centred urbanism and military chiefs. Evidence comes from inscriptions, architecture and foreign travellers, so the political institution in the question should be connected to its precise regional setting. The distractors need separate rejection: Al-Biruni belongs to a different institution, context or chronology; Niccolao Manucci does not perform the function described in the stem; and Ibn Battuta fails the required association. The wording of “Which foreign traveller left a detailed account of Vijayanagara during Krishnadevaraya's reign?” is deliberately specific, so the candidate should isolate its operative clue before recalling names. — Domingo Paes”, but also remember the factual reason stated above.
