Which of the following rulers of the Gupta Empire do the given statements refer to?

1. During the last days of his reign, the Gupta Empire was threatened by the invasion of the White Huns.
2. He issued new coins with images of Lord Kartikeya.

Kumaragupta I (Mahendraditya) was the ruler of the Gupta Empire from 415-455 CE. He retained, intact, the vast empire, which extended from North Bengal to Kathiawar and from the Himalayas to the Narmada. However during the last days of his reign, the Gupta Empire was threatened by the rebellion of Pushyamitras of central India and invasion of the White Huns. However, Kumaragupta was successful in defeating both threats and performed Ashvamedha Yajna (horse sacrifice) to celebrate his victory. He issued new coins with images of Lord Kartikeya. Note: It is statement 2 which helps a student to arrive at the right answer as the reign of Skandagupta (which is a distracter here) too witnessed threats from the Huns.
