A 150 CE inscription of Shaka ruler Rudradaman and a 5th century inscription, at the same place, of the time of Gupta king Skandagupta refer to which one of the following?

The inscriptions found at Junagadh (Girnar) in Gujarat refer to the history of the Sudarshana Lake. The Shaka ruler Rudradaman I issued a famous inscription in 150 CE, recording that the lake was originally constructed by Pushyagupta (governor of Chandragupta Maurya) and later improved by Tushaspa (during Ashoka's reign). Rudradaman repaired the dam after it was destroyed by a storm, notably without imposing extra taxes on his subjects.

Later, in the 5th century (c. 455-458 CE), an inscription of the Gupta King Skandagupta was carved at the same site. it records another major reconstruction of the lake's embankment by his governor Parnadatta and his son Chakrapalita after it burst due to excessive rains. This site provides a unique chronological record of the lake's maintenance across different dynasties.
