Explanation

The correct answer is Option B: To reveal a secret, as the idiom 'spill the beans' is often used to describe the act of divulging hidden or confidential information. For example, if someone accidentally lets out a surprise party plan, they could be said to have 'spilled the beans.' Options A, C, and D are incorrect because they do not capture the meaning of the idiom. Option A relates to cooking rather than disclosure, Option C addresses resource management, and Option D refers to emotional frustration-all of which are unrelated to revealing secrets.
