Select the most appropriate option to fill in blank no. 4.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. by.
The sentence discusses fountains as musical instruments, with the term "played" referring to the action performed on these instruments.
When we talk about playing a musical instrument, we typically use the preposition "by" to denote the performer or agent producing the music.
For example, "played by the pianist," "played by the guitarist," etc.
So, the correct construction is "played by one or more of their water jets."
This implies that the water jets are the agents producing the music, which aligns with the sentence's intended meaning.
