A. is correct --> p. 22, People, skills and competencies, COBIT 2019 Framework Introduction and Methodology

p.22: "People, skills and competencies are required for good decisions, execution of corrective action and successful completion of all activities."

The C. Principles, policies and frameworks component in COBIT is a primary driver for executing corrective actions necessary to achieve governance or management objectives. These principles, policies, and frameworks provide the foundational guidelines and rules that organizations follow to ensure effective governance, compliance, and consistent management of processes and activities. By adhering to these principles and policies, organizations can address deficiencies, improve performance, and align their actions with strategic goals.

While people, skills and competencies, and organizational structures are also important components of COBIT, they are not the primary drivers for the execution of corrective actions

The correct answer is C. Principles, policies and frameworks. COBIT (Control Objectives for Information and Related Technology) is a framework for IT governance and management. The principles, policies and frameworks component of COBIT provides the basis for decision-making and sets the direction for governance and management objectives. It includes the policies, procedures, and guidelines that define the organization's approach to IT governance and management. When corrective actions are required to achieve governance or management objectives, the principles, policies and frameworks component of COBIT provides the guidance necessary to implement those actions effectively. It ensures that the corrective actions align with the overall governance and management objectives of the organization, and that they are carried out in a consistent and effective manner.
