The correct answer is A. May 31, 1981.
The SLV-3 (Satellite Launch Vehicle-3) was a three-stage solid-propellant launch vehicle developed by the Indian Space Research Organisation (ISRO). It was the first Indian launch vehicle to put a satellite into orbit.
The SLV-3 was launched on May 31, 1981, from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The launch was successful, and the SLV-3 put the Rohini satellite into orbit.
The SLV-3 was retired in 1983 after three successful launches. It was replaced by the ASLV (Augmented Satellite Launch Vehicle) in 1987.
The SLV-3 was a significant achievement for ISRO. It demonstrated India’s ability to develop and launch its own launch vehicles. The SLV-3 also paved the way for the development of more advanced launch vehicles, such as the PSLV (Polar Satellite Launch Vehicle) and the GSLV (Geosynchronous Satellite Launch Vehicle).
