What is true of the GSLV-F15 mission by ISRO?

Explanation

On 29 January 2025, ISRO launched GSLV-F15 from Satish Dhawan Space Centre, Sriharikota, as the 100th launch mission from Sriharikota. Through this launch vehicle, the NVS-02 navigation satellite for the NavIC system was placed into a Geosynchronous Transfer Orbit (GTO). The launch and satellite injection into GTO were successful; however, during the later orbit-raising process, the oxidizer valve did not open. Therefore, the satellite could not reach the intended geosynchronous orbit and remained in an elliptical orbit. Now it is not operational. Since both options (a) and (c) are correct, the correct answer is option (d).
