Answer:
D). Jerry looks ill today.
Explanation:
Predicate adjective is described as the adjective in the predicate part of the sentence that accompanies or follows the linking verb of the sentence. Such adjectives function to describe/modify the subject.
As per the question, option D displays the sentence that contains an italicized word 'ill' that is employed as a predicate adjective as it exemplifies the subject complement that comes after the linking verb 'looks' and functions to qualify the subject 'Jerry' in the sentence. Thus, option D is the correct answer.
