B). The writer repeats the word “deadly” so much that it becomes alarming.
Explanation:
The sentence 'the writer....alarming' would most aptly assist in expanding the paragraph and offers evidence that the author opts for a deft style and his descriptions help in making the fact more reasonable and dramatic. <u>The repetition of the word 'deadly' makes the description more frightening and alarming. It gives a hint to the readers that something fatal or shocking is about to happen</u>. Thus, <u>option B</u> is the correct answer.
