The correct answer is option (C):
Gloom
The question asks for the antonym of the word "mirth." Mirth signifies amusement or laughter, often associated with happiness and lightheartedness. To find the best antonym, we need a word that represents the opposite of these feelings.
Let's examine the options:
* Serenity: Serenity implies a state of calmness, peace, and tranquility. While not directly opposed to mirth, it doesn't represent the opposite feeling.
* Triumph: Triumph signifies a victory or success, often accompanied by feelings of joy. This aligns more with the positive feelings associated with mirth, not its opposite.
* Gloom: Gloom indicates darkness, sadness, or a state of depression and unhappiness. This is directly opposed to the joyful and lighthearted nature of mirth, making it the most suitable antonym.
* Newness: Newness refers to something being recently made or discovered. This is unrelated to the emotional state of mirth.
* Gaiety: Gaiety is synonymous with mirth, representing a state of cheerfulness and happiness. This is a synonym, not an antonym.
Therefore, "Gloom" is the correct answer because it accurately represents the opposite emotional state of mirth.
