Explanation

Upgrading to Cloud SQL Enterprise Plus edition is the correct choice to maximize uptime during planned maintenance events. Enterprise Plus provides near-zero downtime maintenance updates, where the instance failovers to a standby replica with sub-second interruption instead of taking several minutes of downtime. It also allows maintenance windows to be configured with more granular control. Option A (automated backups) helps with data recovery after an outage but does not reduce downtime during planned maintenance. Option B (cross-region read replica) improves disaster recovery and read scaling but does not provide automatic failover for planned maintenance. Option D (email notifications) informs you about upcoming maintenance but does nothing to prevent or minimize the downtime itself.
