In which sentence does the prepositional phrase act as an adverb?

A. Last evening, Anne suffered from a headache.
B. The door to the attic was left open.
C. Mr. Frank discussed the problem of noise in the annex.
D. He bought a drink for Mr. Dussel.
Is the answer A?
Thank you

A is correct

Yes, the answer is A. In the sentence "Last evening, Anne suffered from a headache," the prepositional phrase "from a headache" acts as an adverb because it modifies the verb "suffered." To identify the role of a prepositional phrase, you can follow these steps:

1. Identify the prepositional phrase. In this case, the prepositional phrase is "from a headache."
2. Determine what the prepositional phrase is modifying. In this sentence, it modifies the verb "suffered."
3. Determine the role of the modifier. Since the prepositional phrase is modifying the verb by providing information about the manner in which Anne suffered, it is acting as an adverb.
