The correct answer is C. Skandagupta.
Skandagupta was the grandson of Chandragupta II and the son of Ramagupta. He ruled the Gupta Empire from 455 to 467 CE. During his reign, he successfully defended the empire from the Hunas, a nomadic people from Central Asia.
The Hunas were a major threat to the Gupta Empire. They had already conquered much of the northwestern part of the empire, and they were poised to invade the heartland of the empire. Skandagupta was able to defeat the Hunas in a series of battles, and he drove them back to Central Asia.
Skandagupta’s victory over the Hunas was a major turning point in the history of the Gupta Empire. It ensured the survival of the empire and allowed it to continue to flourish for several more decades.
Samudragupta was the founder of the Gupta Empire. He ruled from 335 to 375 CE. He was a great conqueror, and he expanded the empire to its greatest extent. However, he did not have to face the Hunas, as they did not invade India until after his death.
Chandragupta II was the grandson of Samudragupta. He ruled from 375 to 415 CE. He was a great ruler, and he is considered to be the golden age of the Gupta Empire. However, he did not have to face the Hunas, as they did not invade India until after his death.
Ramagupta was the son of Chandragupta II. He ruled for a short time from 415 to 416 CE. He is best known for being defeated by the Huna leader, Mihirkula.
In conclusion, the correct answer is C. Skandagupta. He was the only Gupta ruler who had to face the Hunas, and he was the only one who was able to defeat them.
