Why each option

When a vulnerability scan reveals findings on critical internal systems, the product owner must perform a business impact assessment to weigh operational risk against patching disruption before remediation proceeds.

AThe product owner should perform a business impact assessment regarding the ability toCorrect

A business impact assessment by the product owner is the most appropriate corrective action because vulnerability findings on internal hosts often affect systems critical to business continuity, where immediate patching may cause downtime or service disruption. The product owner is best positioned to evaluate whether the organization can tolerate the residual risk of leaving the vulnerability unpatched versus the impact of applying a fix. This assessment drives an informed, risk-based remediation decision aligned with business priorities.

BThe application developer should use a static code analysis tool to ensure any application code is

Static code analysis addresses weaknesses in application source code, but a vulnerability scan finding on an internal host is most likely an infrastructure or OS-level issue that static analysis tooling cannot detect or remediate.

CThe systems administrator should evaluate dependencies and perform upgrades as necessary.

Evaluating dependencies and upgrading is a valid technical remediation step, but it should follow a business impact assessment so the organization understands operational consequences before making potentially disruptive system changes.

DThe security operations center should develop a custom IDS rule set to prevent attacks using

Developing a custom IDS rule set is a detective and compensating control, not a corrective action - it may reduce exposure temporarily but does not remediate the underlying vulnerability identified by the scan.
