Explanation

Cloud SQL allows you to configure a maintenance window - a specific day and hour each week when Google can perform disruptive maintenance on your instance. By setting this window to non-business hours (e.g., late night or weekends), you ensure maintenance events happen when traffic is low and impact is minimal. This is the direct, built-in solution for controlling when planned maintenance occurs. Option B (migrating to Cloud Spanner) is an extreme overreaction to a maintenance scheduling issue. Option C (contacting Support) is reactive, not preventive. Option D is invalid - Cloud Scheduler cannot manage Cloud SQL maintenance windows.
