Even though she was inexperienced, Ayesha bravely agreed to lead the project, but when unexpected difficulties arose, she realized that she had truly bitten off more than she could chew.What does the underlined idiom mean?

Explanation

The idiom 'bitten off more than she could chew' means to take on a task that is too challenging or beyond one's capabilities. In the context of the question, Ayesha, despite her inexperience, attempts to lead the project and encounters difficulties that reveal her limitations. Option B is correct as it aligns perfectly with this interpretation. The other options are incorrect because they either focus on unrelated actions (Options A and D) or misinterpret the context of confidence versus capability (Option C). Thus, the idiom highlights the challenge of overcommitting oneself.
