What is the test for sustaining an objection to a question on the grounds of relevancy?

"A witness may not be examined on matters that are irrelevant to the issues in the case." (People v. Mayfield (1997) 14 Cal.4th 668, 755.) In determining whether the trial court erred in sustaining an objection to a question during the examination of a witness made on the grounds of relevancy, we apply an abuse of discretion standard of review. (People v. Alvarez (1996) 14 Cal.4th 155, 205 [applying an abuse of discretion standard of review when considering whether the trial court properly sustained an objection to a question during trial examination on the ground that any response would be irrelevant].)
