Which of the following Gupta kings stopped the Huns from invading India?

Answer: Option C

The Gupta Empire in India reigned in the Ganges basin during the 5th century, and the Kushan dynasty occupied the area along the Indus. After defeating the Kushanas, the Hunas entered the subcontinent from the Kabul valley. They entered Punjab and the Gupta Empire failed to protect the northeast frontier of the empire and this made easier for the Huns to enter an unguarded entrance in the Gangetic valley, just into the heart of the Gupta Empire. This was in 458 AD. The Hephthalites, known as the Hunas in India kept on invading India until the Gupta ruler Skandagupta repulsed them. The Hunas, under the leadership of Toramana, suffered a crushing defeat by the Gupta emperor Skandagupta.
