Explanation:

Communication Satellites of India
CMS-01: ISRO is gearing up for the launch of India’s communication satellite CMS-01 using the rocket PSLV-C50.

• India’s new communication satellite CMS-01 will be positioned into the geosynchronous transfer orbit.
• Generally, communication satellites are heavier and therefore the PSLV rocket carrying it requires an extra thrust to take them to the geo-synchronous transfer orbit.

The satellite CMS-01 will have transponders that will be useful in covering mainland India and also far-flung island territories of Andaman and Nicobar and the Lakshadweep for communication purposes.

• GSAT: The GSAT (Geostationary Satellite) satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting.
• As of now 20 GSAT satellites of ISRO have been launched out of which 14 satellites are in service.
• INSAT: The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit.
• The INSAT system with more than 200 transponders, it provides services to telecommunications, television broadcasting, satellite newsgathering, societal applications, weather forecasting, disaster warning and Search and Rescue operations.

Note: IRNSS is an independent regional navigation satellite system being developed by India.  RISAT (Radar Imaging Satellite) is a series of Indian radar imaging reconnaissance satellites built by ISRO.

Hence option 2nd is correct.
