Which of the following is basic feature of the rule of law?

The basic feature of the rule of law is "Equality before the law." This means that all individuals, regardless of their status, wealth, or power, are subject to the same laws and legal procedures. No one is above the law, and everyone should be treated equally and fairly under the law. This ensures that there is no discrimination or favoritism in the legal system, and it promotes justice and fairness in society. The other options mentioned in the question, such as secret trials of offenders, executive control of the judiciary, and unlimited powers for the police, are not basic features of the rule of law, and may even be seen as violations of the rule of law.
