You use Azure Security Center.

In Azure Security Center (now integrated into Microsoft Defender for Cloud), when you receive a security alert, you can view details and recommended remediation actions directly within the portal. According to Microsoft documentation, each alert in Security Center provides two main sections when you choose Take Action:

Mitigate the threat – steps to remediate the immediate incident.

Prevent future attacks – recommendations generated by Defender for Cloud to strengthen your security posture and avoid similar alerts in the future.

To specifically view recommendations to resolve the alert, you expand the Prevent future attacks section. This section includes actionable insights such as enabling Just-In-Time (JIT) VM access, applying system updates, adjusting network security group rules, or enabling endpoint protection.

Other options are incorrect:

The Mitigate the threat section focuses on immediate containment, not preventive recommendations.

Regulatory compliance and Recommendations pages are general assessments, not alert-specific recommendations.

Therefore, the correct answer is A — select the alert → Take Action → expand Prevent future attacks.
