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.
