Answer:
B. Phew! That falling piano nearly landed on me!
Step-by-step explanation:
An exclamation mark is used to denote or express a sudden, shocking, surprising, or even strong feeling. The exclamation mark is set by the use of the sign "!" after the end of the sentence or word.
Among the given sentences, the correct use of the exclamation is sentence B. In this sentence, the word exclaimed is "phew" which denotes a feeling/expression of relief and also the realization that "the piano almost fell on [the speaker]". So, the use of the exclamation mark at the end of both words/sentences is the correct construction.
Thus, the correct answer is option B.
