Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. on the efficacy under cognitive-behavioural therapy.
The preposition "under" is incorrect in "on the efficacy under cognitive-behavioural therapy."
The correct preposition to use is "of."
Of is a preposition, that commonly introduces prepositional phrases which are complements of nouns, creating the pattern: noun + of + noun.
The sentence should read "on the efficacy of cognitive-behavioural therapy."
