The OECD's Principles of Corporate Governance insists on: greater immunity power for corporate managers. lesser transparency within corporate structures. greater concealment of corporate governance policies to avoid conflicts of interest. greater protection for whistleblowers.

The correct answer is letter "D": greater protection for whistleblowers.

Explanation:

The Organisation for Economic Co-operation and Development (OECD) is an intergovernmental organization that aims to promote economic progress and worldwide trade. The OECD established the Principles of Corporate Governance to improve the legal, regulatory, and institutional framework.

The OECD Principles include ensuring effective corporate governance, equal treatment to shareholders, and disclosure and transparency. Because of the recent U.S. whistleblower situation and in an attempt to maintain investors' confidence the OECD enhanced the transparency principle granting more protection to whistleblowers.
