A general support system is considered a major information system when special regulatory attention is required. The correct answer to this question is D) Regulatory. Major information systems within organizations often have significant compliance and regulatory requirements to ensure the protection of sensitive data and the integrity of system operations.
Regulatory bodies or standards such as HIPAA for healthcare information, Sarbanes-Oxley for financial reporting, or GDPR for data protection in the European Union, may impose specific requirements that necessitate special attention to these systems.
