Which of the following measures best demonstrate the rooms free of officials gaining too much powers

1) Implementing regular performance evaluations for officials to ensure they are carrying out their duties effectively and not abusing their powers.

2) Implementing transparency measures such as open meetings and public access to information, to ensure that officials are held accountable and their powers are not being abused.

3) Establishing an independent oversight body, such as an ethics commission or ombudsman, to investigate complaints against officials and ensure they are following proper procedures.

4) Implementing checks and balances within the system, such as requiring multiple officials or departments to review and approve decisions, to prevent any one individual from gaining too much power.

5) Promoting a culture of whistleblower protection, where officials and employees are encouraged to report any abuses of power they witness without fear of retaliation.

All of these measures, when implemented together, can help demonstrate that officials are not gaining too much power and that there are mechanisms in place to prevent and address abuses of power.
