The correct option is Tailor the security controls to the system's particular requirements and risk profile.

Tailor the security controls to the system's particular requirements and risk profile is correct because NIST SP 800-53 provides baseline control families and explicitly expects organizations to select and modify those baselines based on the system impact level and the organization risk assessment. Tailoring allows you to apply scoping statements overlays and compensating controls so that controls are appropriate and effective for the specific system and threat landscape.

When you Tailor the security controls to the system's particular requirements and risk profile you start with a baseline then document any additions deletions or adjustments and provide justification. This approach keeps controls cost effective and aligned with risk while ensuring required protection objectives are met.

Implement all controls at the greatest level of stringency possible is incorrect because applying every control at maximum stringency is rarely practical and it ignores risk and operational impact. That approach can create unnecessary burden and may reduce overall security by introducing complexity and implementation gaps.

Deploy only the least set of controls deemed necessary is incorrect because selecting the bare minimum of controls without a structured baseline and tailoring process risks underprotection. NIST recommends using baselines and a documented risk assessment to guide which controls are necessary and how they should be applied.

Cloud Security Command Center is incorrect because that is the name of a cloud security product and not a recommended method for applying NIST SP 800-53 controls. It is not an approach to tailoring or selecting controls under the NIST framework.
