Show answer & explanation
Correct answer: A
Answer: GSAT-18 is an Indian geostationary telecommunication satellite used to provide communication and broadcasting services.
Primary purpose: Provide telecommunication services (uses C- and Ku-band transponders) for applications such as direct-to-home broadcasting and data/VSAT links.
Launch fact: GSAT-18 was launched in October 2016 on an Ariane 5 vehicle (geostationary communication satellite).
Why the other choices are incorrect: Astronomical observations are carried out by telescopes and space observatories; pollution monitoring is done by Earth observation satellites; weather monitoring is handled by meteorological satellites. GSAT-18’s design and payload are for communications, not for these purposes.
