Correct option is A
The correct answer is
(a).
Explanation:
The error lies in the use of "story." Since the phrase "one of the most captivating" suggests more than one story, the correct noun form should be "stories" (plural). The noun should agree with the subject.
Corrected sentence:
"Her latest novel is considered one of the most captivating
stories in contemporary literature, earning praise for its intricate plot and well-developed characters."
