Final answer:
The correct answer is c) Chief Information Officer (CIO), who is responsible for managing and maintaining an organization's information systems to align with strategic goals.
Step-by-step explanation:
The person who heads the department responsible for managing and maintaining information systems, and ensuring they support the organization's strategic goals is the Chief Information Officer (CIO). The CIO plays a critical role in aligning the company's IT infrastructure with its overall business strategy, overseeing the development and implementation of information systems that fulfill organizational needs. Roles such as the Chief Executive Officer (CEO) and Chief Operating Officer (COO) might work closely with the CIO to ensure that the IT strategy is in line with the business goals, but the CIO is the primary executive responsible for the information systems domain.
