Not attemptedCorrect Answer: (a) 1 only
1) ISRO successfully conducted a 50-second hot test of its indigenously developed cryogenic stage on 28 October 2006, validating statement 1. ([timesofindia.indiatimes.com](https://timesofindia.indiatimes.com/india/india-conducts-first-cryogenic-rocket-test/articleshow/205907.cms?utm_source=openai)) 2) Europe’s Ariane rockets (HM7B engine, in service since 1979) and Japan’s H-II rockets had long used cryogenic stages, so India was not the only nation after the USA, Russia and China with this capability, making statement 2 incorrect. ([en.wikipedia.org](https://en.wikipedia.org/wiki/HM7B?utm_source=openai)) Therefore only statement 1 is correct.
