Which one of the following statements about Chandragupta II is not correct?

Chandragupta II, also known as Vikramaditya, was a prominent Gupta ruler who expanded his empire through both military conquests and strategic matrimonial alliances [t2][t4]. He married Kubera Naga, a princess of the Naga dynasty, to secure his northern frontiers [t2]. His most significant diplomatic marriage was that of his daughter, Prabhavatigupta, to the Vakataka king Rudrasena II [t2][t3]. This alliance was crucial as it allowed the Guptas to exert indirect control over the Deccan and facilitated the conquest of the Shaka territories in Western India [t2][t5]. The statement that she married an Ahom prince is incorrect, as the Ahom kingdom was established in Assam much later, in the 13th century. Additionally, his court was renowned for the 'Navaratnas' (nine gems), which included the legendary poet Kalidasa and the lexicographer Amarasimha, author of the Amarakosha [t2][t6].
