Answer 1

Hint:- For the monitoring of floods and to provide knowledge on Sudarshan Lake that the lake was an artificial reservoir, the Junagarh rock inscription was constructed. Rudradaman's Junagarh rock inscription was also known as Rudradaman's Girnar Rock inscription.

Complete step by step answer:-
From the era of Chandragupt Maurya to the time when the inscription was written, the eight lines of the historical record of water control and irrigation conduits at Sudarshan Lake. This lake is constructed at Junagadh Gujarat. These preserved are located near Girnar hill, junagadh. This lake was built because the king wanted the best irrigation facilities and control over his citizens in his kingdom. The Shakra ruler Rudradaman 1 repaired the lake in 150 AD, and under the rule of Skandagupta (415AD-455AD), his governor Parramatta repaired the lake again.
Rudraadaman's Junagarh rock inscription says that Pushyagupta built a dam on the Sudarshan lake for irrigation. Sudarshan lake was founded by Pushyagupta, the governor of Saurashtra under Chandragupta Maurya.
The Sanskrit edict notes the repairs carried out on Sudarshan Lake by Mahakshtrap Rudraman. There are numerous edicts that talk about the repairs, but the Sanskrit Junagadh inscription credits rudradaman during 150 CE. Pushyagupta, the governor during the rule of Chandragupta Maurya, built the dam on the Sudarshan lake for irrigation.

Thus, B Pushyagupta option is correct.

Note:- During the rule of the Mauryas, the whole inscription by a local governor mentions the lake, with embankments and water channels. Rudradaman was a ruler and he claimed that he had would have his own money to improve the lake.
