Answer:
C.
Explanation:
A misplaced modifier can be defined as misusing of word or phrase in a sentence, or improper placement of words that modifies.
A modifier is a word, phrase, or clause that is used to describe or explain another word. An adjective and adverb serves as a modifier.
From the given options, the modifier is misplaced in the third sentence. It is because the modifier 'served' is improperly placed in the sentence.
The correct sentence should be:
"She served the children sandwiches on paper plates."
So, the correct answer is the third option.
