The criminal finally decided to spill the beans about his partners.What does the underlined idiom mean?

Explanation

The idiom 'spill the beans' means to reveal a secret or disclose information that was meant to be kept confidential. In the context of the question, the criminal decided to 'spill the beans' about his partners, indicating that he chose to share information about them, likely as part of a confession or deal with authorities. The other options do not align with the definition of the idiom. 'To waste food' incorrectly interprets the phrase, while 'to hide information' directly contradicts it. 'To play tricks' is unrelated to the concept of revealing secrets or information.
