With reference to the scholars/litterateurs of ancient India, consider the following statements: 1. Panini is associated with Pushyamitra Shunga. 2. Amarasimha is associated with Harshavardhana. 3. Kalidasa is associated with Chandra Gupta - II. Which of the statements given above is/are correct?

Let's examine each statement:

1. Panini is associated with Pushyamitra Shunga. This statement is incorrect. Panini, the renowned Sanskrit grammarian who authored the Ashtadhyayi, lived much earlier, around the 5th to 4th century BCE. Pushyamitra Shunga founded the Shunga dynasty in the 2nd century BCE, meaning Panini predates him by several centuries.
2. Amarasimha is associated with Harshavardhana. This statement is incorrect. Amarasimha, the author of the Amarakosha (a Sanskrit lexicon), was one of the 'Navaratnas' (nine gems) in the court of Chandragupta II (Vikramaditya) of the Gupta dynasty, who reigned in the late 4th to early 5th century CE. Harshavardhana ruled in the 7th century CE, much later than Amarasimha.
3. Kalidasa is associated with Chandra Gupta - II. This statement is correct. Kalidasa, one of the greatest Sanskrit poets and dramatists, is widely believed to have been a prominent figure in the court of Chandragupta II (Vikramaditya), during the golden age of the Gupta Empire. His works like Abhijnanasakuntalam and Meghaduta are masterpieces of that era. Therefore, only statement 3 is correct.
