Correct Option: D. Initiation of bills Explanation of the Correct Answer The judicial arm of government, often referred to as the judiciary, is primarily responsible for interpreting laws, ensuring justice, and protecting the rights of individuals. Its main functions include:

1. Interpretation of the Law (Option A): The judiciary interprets laws passed by the legislative arm. This means that when there are disputes about what a law means or how it should be applied, it is the role of the courts to clarify these issues.
2. Judicial Review (Option B): This function allows the judiciary to review laws and actions of the executive and legislative branches to ensure they comply with the constitution. If a law is found to be unconstitutional, the judiciary has the power to nullify it.
3. Checking of Arbitrariness (Option C): The judiciary serves as a check on the powers of the other branches of government. This means that if the executive or legislative branches act in a way that is arbitrary or violates individual rights, the judiciary can intervene to protect citizens.

Initiation of Bills (Option D) is not a function of the judiciary. This task is typically the responsibility of the legislative arm of government, which is responsible for creating, debating, and passing laws. The judiciary does not have the authority to propose or initiate legislation; its role is to apply and interpret the laws that have already been enacted. Explanation of Why Other Options Are Incorrect or Weaker

• Option A: Interpretation of the law: This is a fundamental function of the judiciary. Without this role, there would be no mechanism to resolve disputes regarding the meaning of laws, leading to chaos and inconsistency in the application of justice.
• Option B: Judicial review: This is a critical function that ensures the rule of law is maintained. It allows the judiciary to act as a guardian of the constitution, ensuring that no law or government action can violate constitutional principles.
• Option C: Checking of arbitrariness: This function is essential for protecting individual rights and maintaining a balance of power among the branches of government. It prevents any branch from overstepping its authority and ensures that citizens have a recourse if their rights are infringed upon.
