The correct answer is: Tranquility.
The word "tranquillity" means a state of peace and quiet. It is derived from the Latin word "tranquillus," which means "calm." The word "tranquillity" is often used to describe a place or situation that is free from noise, disturbance, or excitement. It can also be used to describe a person who is calm and composed.
The other options are incorrect because they are not spelled correctly. The word "trenquillity" is missing an "a" in the middle. The word "trenquility" is missing an "e" at the end.
I hope this helps!
