Which one of the following statements about reusable space vehicle of ISRO is not correct?

In June 2016, ISRO successfully launched India's first reusable space vehicle.
The space vehicle was launched from Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.
The reusable launch vehicle climbed to a height of 65 km before automatically steering back for landing.
The vehicle was initially boosted by a rocket that contained liquid fuel.

Statements A, B, and C are correct descriptions of ISRO’s first reusable launch vehicle test flight (RLV-TD) conducted in June 2016. It was India’s first reusable space vehicle demonstrator (Hypersonic Flight Experiment – HEX). It was launched from Sriharikota. It reached an altitude of about 65 km before descending and making a simulated landing in the Bay of Bengal. Statement D is incorrect. The RLV-TD was initially boosted by a solid rocket motor (HS9), not a rocket containing liquid fuel.
The ISRO RLV-TD test in 2016 was a significant step towards developing reusable launch vehicle technology, demonstrating hypersonic flight, aero-thermodynamic characterisation, and autonomous navigation for return flight.
The RLV-TD is a scaled-down technology demonstrator. Subsequent tests are planned to evaluate technologies like landing and re-entry. The eventual goal is a two-stage-to-orbit (TSTO) fully reusable vehicle. The initial boost from a solid motor was sufficient for this experimental flight to reach the desired altitude and velocity for the demonstration.
