Answer:
The sentence that contains a misplaced modifier is the following one: The flight was postponed by bad weather for which I had a ticket.
Step-by-step explanation:
A misplaced modifier is a word, phrase, or clause that is separated from the word it modifies or describes. Because of this separation, sentences with this mistake sound awkward. In this case, the misplaced prepotional phrase "for which I had a ticket" is the misplaced modifier. To fix the error and clarify the mistake, the PP should be placed after the word it modifies, "flight".
