Who among the following rulers of the Gupta Empire is identified by Kalidasa with the legendary Vikramaditya?

Option 1 -> Chandragupta-I was the founder of the Gupta Empire but is not associated with the Vikramaditya legend.

Option 2 -> Samudragupta, known for his military conquests, is not identified with Vikramaditya by Kalidasa.

Option 3 -> Chandragupta-II adopted the title Vikramaditya and is identified with the legendary king by Kalidasa, who was part of his court.

Option 4 -> Kumaragupta-I, son of Chandragupta-II, ruled later and is not connected to the Vikramaditya legend.

Hence, Option 3: Chandragupta-II -> Kalidasa, the renowned Sanskrit poet and dramatist, was one of the Navaratnas (nine gems) in Chandragupta-II's court. Chandragupta-II (ruled c. 380-415 CE) adopted the title "Vikramaditya" and is widely identified with the legendary king Vikramaditya known for his wisdom, valor, and patronage of learning -> correct
