Maintenance and inspection records support which?

Answer: A — Warranty claims and accident investigations

Maintenance and inspection records provide a documented history of a vehicle’s upkeep, showing that required service and safety checks have been performed. This history is what warranty providers rely on to verify eligibility for coverage, making it easier to support warranty claims when a covered issue arises. In an accident investigation, those records help determine whether a mechanical problem contributed to the incident or if regular maintenance prevented a failure, aiding the overall assessment of liability and cause. The remaining options don’t align with the purpose of maintenance records—records aren’t used to schedule crew events, run marketing campaigns, or directly obtain insurance discounts.
