India’s first experimental satellite launch vehicle was the SLV-3 (Satellite Launch Vehicle-3). 
It was developed by ISRO (Indian Space Research Organisation) under the leadership of Dr. A.P.J. Abdul Kalam. 
SLV-3 successfully launched Rohini Satellite RS-1 into near-Earth orbit on July 18, 1980, from Sriharikota. 
This event marked India’s entry into the exclusive group of nations capable of developing and launching satellites independently. 
Now evaluating the options: 
(A) GSLV — Refers to Geosynchronous Satellite Launch Vehicle, developed later. ❌ 
(B) ASLV — Augmented Satellite Launch Vehicle, a later experimental vehicle. ❌ 
(C) SLV3 — ✔️ Correct. It was India’s first experimental launch vehicle. ✅ 
(D) None of these — Incorrect, as SLV-3 is the right answer. ❌ 
Hence, the correct answer is option (C).
