Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. playfulness.
Context: The sentence talks about something that reduces stress and enhances happiness. The subject of the sentence must be a noun that refers to a quality or state.
Meaning of the words:
Playfully is an adverb that describes how an action is done, not a subject.
Playfulness is a noun that refers to the quality of being fun, light-hearted, or full of play.
Played is the past tense of the verb “play” and doesn’t fit grammatically as a subject here.
Plays is the present tense verb form, which requires a subject and doesn't fit the structure of this sentence.
Correct word: Playfulness
Reason: The sentence requires a noun as the subject to match the verb “brings down”. “Playfulness” is the quality being discussed — the idea that playfulness lowers stress and increases happiness.
“Playfully” is an adverb and cannot function as the subject.
“Played” and “plays” are verb forms, not suitable in this structure.
Only “playfulness” fits grammatically and contextually as the subject.
Final Sentence: There is a fantastic body of evidence which indicates that playfulness brings down the stress chemical and it enhances the happiness chemical.
Hence, the chosen option will be correct.
