Which one of the following is not a feature of F.M. Marx’s guardian bureaucracy ?

Guardian bureaucracy claims competence and custodianship of public interest, often paternalistically; corruption is not its defining feature. Therefore, ‘Corrupt’ is the correct choice because it does not satisfy the condition in the question, whereas ‘Custodian of Public interest’, ‘Competent’, and ‘Authoritarian’ represent valid features or accurate associations in this context.
