Explanation:

Other than USA and Russia, India is the only country to have launched a similar observatory into space: This statement is incorrect. Prior to India, several other countries and regions besides the USA and Russia, such as the European Space Agency (ESA), Japan, and China, had launched space-based astronomical observatories.

Astrosat is a 2000 kg satellite placed in an orbit at 1650 km above the surface of the Earth: This statement is also incorrect. Astrosat, India's first dedicated multi-wavelength space observatory, was launched into a near-Earth, equatorial orbit, but not at 1650 km. Its orbit is much lower, at an altitude of about 650 km.

Therefore, the correct answer is 4. Neither 1 nor 2.
