Show answer & explanation
Correct answer: D
Explanation
The correct antonym for the word superficial is ‘Deep’.
Superficial refers to something that is on the surface, shallow, or lacking depth (both physically and intellectually).
Deep is the direct opposite, referring to something that extends far down from the surface or has great intellectual/emotional weight.
The other options—Shallow, Surface, and External—are all synonyms or related terms to superficial, rather than opposites.
