The correct option "Neither 1 nor 2" is accurate because, firstly, while India is one of the few countries to have launched a dedicated astronomical observatory, several other nations, including countries like Japan and China, have also developed and deployed similar satellites. Thus, the first statement is misleading. Secondly, Astrosat is actually placed in a low Earth orbit at about 650 km, not 1650 km, making the second statement incorrect. This is significant for UPSC Prelims as it tests candidates' understanding of both India's space capabilities and the operational details of satellite deployments, which are key topics in the context of India's advancements in science and technology.
