With reference to the Junagadh inscription of Rudradaman, consider the following statements : 1. The script of this inscription is Kharosthi and the language is Prakrit. 2. The inscription records the restoration of a reservoir called Sudarshana Lake. 3. It is an undated inscription. Which of the statements given above is/are correct?

Only statement 2 is correct. The Junagadh rock inscription of Rudradaman I (c. 150 CE) records the repair of the Sudarshana Lake dam, originally constructed during Chandragupta Maurya's reign and later improved by Ashoka. Statement 1 is wrong — the inscription is in Sanskrit (the first major inscription in chaste Sanskrit) and is written in the Brahmi script, not Kharosthi/Prakrit. Statement 3 is wrong — the inscription is dated to the year 72 of the Saka era (approximately 150 CE).
