Gupta inscription inscribed above the Girnar inscription of Rudradaman is dated to:

5th Century C.E.

The correct answer is Option (3) → 5th Century C.E.

Girnar inscription- The Sudarshana lake was an artificial reservoir. We know about it from a rock inscription (c. second century CE) in Sanskrit, composed to record the achievements of the Shaka ruler Rudradaman. The inscription mentions that the lake, with embankments and water channels, was built by a local governor during the rule of the Mauryas. However, a terrible storm broke the embankments and water gushed out of the lake. Rudradaman, who was then ruling in the area, claimed to have got the lake repaired using his own resources, without imposing any tax on his subjects. Another inscription on the same rock (c. fifth century) mentions how one of the rulers of the Gupta dynasty got the lake repaired once again.
