What is being asked for when someone requests an opinion?

When someone requests an opinion, they are typically looking for feedback. Feedback refers to a person's thoughts, views, or suggestions based on their perception of a situation, idea, or performance. It invites a subjective perspective, allowing an individual to share their impressions or evaluations.

The other options present different concepts: criticism often implies a negative judgment rather than a constructive opinion; conclusion suggests a final decision or summary rather than an initial response; and consensus refers to a general agreement among a group, which is not the same as an individual opinion. Thus, feedback is the most appropriate choice when someone is seeking an opinion.
