The correct choice is It speeds up detection and enables prompt containment and remediation of threats.

Close coupling between continuous monitoring and incident response shortens the time between when telemetry indicates suspicious activity and when actions are taken. Continuous monitoring supplies timely alerts and contextual data while integrated incident response provides playbooks and automation to contain and remediate threats. Together they reduce dwell time and limit business impact by enabling faster, more consistent handling of incidents.

It increases the number of low severity alerts received is incorrect because tighter integration is intended to improve prioritization and triage rather than to create more low value noise. Automation and enrichment usually reduce the analyst workload on trivial alerts and surface higher priority incidents faster.

It centralizes telemetry into Cloud Security Command Center is incorrect because the benefit described is about detection and response integration and not about a single vendor product. Cloud Security Command Center is a specific GCP service and using it is neither required nor implied for achieving faster detection and containment.

It reduces the amount of required cross team collaboration is incorrect because close coupling often requires coordinated processes and jointly developed playbooks across monitoring, security operations, and response teams. Automation may shift how teams interact but it does not eliminate the need for collaboration.
