The correct answer is None of the above. The Vakataka Empire was an Indian subcontinent dynasty that arose from the Deccan in the mid-3rd century CE. Their state is thought to have stretched from the northern borders of Malwa and Gujarat to the Tungabhadra River in the south, as well as from the Arabian Sea in the west to the eastern borders of Chhattisgarh. After Pravarasena I, the Vakataka dynasty was divided into four branches, two of which are recognized and two of which are unknown. The Pravarapura-Nandivardhana branch and the Vatsagulma branch are the two known branches. Important PointsThey were the most important Satavahana successors in the Deccan and lived at the same time as the Guptas in northern India. It was not after the weakening of Satavahanas that Vakataka came into power, these dynasties were existing in parallel timelines. Hence option (i) is incorrect. Vindhyashakti (250-270), whose name is taken from the deity Vindhyavasini, was the Vakataka dynasty's founder. Hence Option (ii) is incorrect. Pravarasena I (270-330), the next monarch, kept the kingdom a strong power. Pravar Sen was the son of Vidhya Sakti. Hence option (iii) is incorrect. He was the first Vakataka ruler to name himself a Samrat (universal ruler) and wage battles against the Naga rulers.
