Explanation:

Alright, let’s break this down:

- Statement 1: India did launch its first full-fledged meteorological satellite, named METSAT (later called KALPANA-1), in September 2002. That’s accurate.

- Statement 2: Here’s where things get tricky. PSLV-C4 did carry a payload of more than 1000 kg (specifically, Kalpana-1 weighed 1060 kg), but it was placed in a *geosynchronous transfer orbit* (GTO), not directly into a *geosynchronous orbit* (GSO). The PSLV isn’t built to directly inject satellites into geosynchronous orbits; that’s usually the job of the GSLV.

- Option 1: Only 1 – Correct, because only statement 1 holds up 100%.

- Option 2: Only 2 – Not right, because the orbit detail is off.

- Option 3: Both 1 and 2 – Not quite, as explained above.

- Option 4: Neither 1 nor 2 – That’s not true; statement 1 is right.

So, the right answer is Option 1: Only 1
