Security incidents could remain unnoticed and unremediated for long periods is the correct option.

When monitoring alerts are not integrated into an incident management workflow there is no guaranteed assignment, escalation, or tracking for each alert. That lack of a formal process means Security incidents could remain unnoticed and unremediated for long periods which increases dwell time and the likelihood of greater impact from breaches or failures.

Cloud Monitoring is incorrect because it names a monitoring product or category rather than describing an operational risk that results from failing to tie alerts into incident workflows. The question asks for an outcome rather than a tool name.

Alerts may be auto-cleared by the monitoring system without any action is incorrect because automatic clearing is a possible configuration behavior but it does not directly describe the overarching operational risk of missing or unmanaged incidents. The core issue is lack of incident handling, not the specific mechanics of alert lifecycle.

Alert queues may become congested and slow the response process is incorrect because queue congestion is an infrastructural performance problem that can affect responsiveness. It does not most directly capture the persistent operational risk of security incidents remaining unnoticed and unremediated when alerts are not tied into incident management workflows.
