Which of the following is considered court-approved information that juries can deliberate on?

The correct choice is evidence, as it refers to any material or information presented in a legal proceeding that is deemed admissible by the court. Evidence can include physical objects, documents, witness testimonies, and other relevant materials that support a party's argument in a trial. The key aspect of evidence is that it must adhere to certain rules and standards established by the legal system, ensuring that it is reliable and pertinent to the case being deliberated.

In this context, testimonial statements might be considered a form of evidence, but they alone don't encompass the broader category of admissible information referred to in the question. Legal opinions typically represent an interpretation or conclusion based on law rather than facts or substantiated claims that can be presented to a jury. Expert witness insights can provide knowledge based on expertise, yet they are part of the evidence presented in court rather than standalone information. Thus, the comprehensive nature of evidence makes it the primary category that juries rely on during deliberation.
