Why each option

The most reliable validation of a new control's effectiveness and proper implementation comes from an objective, independent internal audit review of its design and operational aspects.

AApproval of the control by senior management

Senior management approval indicates organizational buy-in but doesn't validate the technical design or operational effectiveness of the control.

BComplete and accurate documentation of control objectives

Complete and accurate documentation is essential but only describes the control; it doesn't validate its actual functioning or effectiveness.

CControl owner attestation of control effectiveness

Control owner attestation is a statement of belief or compliance by the person responsible for the control, but it lacks the independence and rigorous testing that an audit provides for true validation.

DInternal audit review of control designCorrect

An internal audit review provides an independent, objective assessment of whether the control is designed appropriately to meet its objectives and is operating as intended. This review typically includes testing and verification, making it the most reliable method of validation compared to self-attestation or documentation.
