Comprehensive and Detailed Explanation (ECIH-aligned):

This scenario reflects a compromised web application, likely due to injection attacks or file upload exploitation. The ECIH Web Application Incident Handling module emphasizes that containment must prevent further attacker access and stop malicious execution.

Option A is correct because identifying injection points and isolating affected components halts further exploitation and allows forensic investigation. ECIH warns against restoring or re-enabling applications without understanding the attack vector, as this often leads to reinfection.

Options B and C do not address security. Option D risks reintroducing malware if vulnerabilities remain.

Thus, targeted isolation and vulnerability identification is the correct containment action.
