The correct answer is option-2, the Sungas. After the decline of the Mauryan Empire, the Sunga dynasty emerged as the next ruling dynasty in India. The Sungas ruled from around 185 BCE to 73 BCE. They were able to establish their power in Magadha, the heartland of the Mauryan Empire. The founder of the Sunga dynasty was Pushyamitra Sunga, who was the commander-in-chief of the Mauryan army. He assassinated the last Mauryan ruler, Brihadratha, and established his own rule. The Sungas ruled for a relatively short period, but they contributed to the revival of Hinduism and Indian culture. They were eventually overthrown by the Kanvas, another dynasty that succeeded them in power.
