Which principle is key for the governance and management of enterprise IT?

COBIT 5 is built upon five key principles for the governance and management of enterprise IT. "Enabling a Holistic Approach" is the fourth principle. It posits that effective governance and management require a comprehensive, integrated view of the enterprise. This is achieved by considering seven categories of enablers: Principles, Policies and Frameworks; Processes; Organisational Structures; Culture, Ethics and Behaviour; Information; Services, Infrastructure and Applications; and People, Skills and Competencies. These enablers work together to support the achievement of enterprise goals.

A. Managing IT Operations is a specific management process domain within the COBIT 5 framework (e.g., DSS01), not one of the five overarching principles.
B. Resource optimization is a primary governance objective and a key goal within the COBIT 5 goals cascade, but it is not one of the five foundational principles.
D. Information is one of the seven critical enablers considered in the holistic approach, but "Managing Information" itself is not a COBIT 5 principle.
