Q1. Which day has been declared as the 'National Space Day' in India?
Explanation
India declared 23 August as National Space Day to mark the successful landing of Chandrayaan-3 near the Moon's south polar region on 23 August 2023. That date is therefore the relevant commemorative day for this 2024 CET current-affairs question. The other August dates listed do not correspond to the declared National Space Day. 20 August, 25 August, and 27 August may be calendar dates around the event, but they are not the officially declared observance. The official key correctly retains 23 August.
