Replace the underlined word with a suitable word:
The serenity of the place overwhelmed me.

Serenity refers to the state of being calm, peaceful, and untroubled. Among the given options, Calmness best captures this meaning. While "noiselessness" implies silence, it doesn't convey the profound peace of mind associated with serenity. "Isolation" and "seclusion" both mean being isolated or hidden away from others, which alters the essence of the sentence.
