Answer:
Statues of Buddhist divine figures could spiritually benefit everyone is the correct answer.
Step-by-step explanation:
The inscription is divided in two paragraphs. In the second one, the speaker mentions all the accomplishments gotten by the King. In the first one, the closure provides the answer by saying that the statue was dedicated to Amoghapasa "for the benefit and salvation and happiness of all creatures."
This way, everyone gets a benefit.
