One of the functions of the judiciary is

Step 1: Analyze the question The question asks for a function of the judiciary, the arm of government made up of the courts and judges.

Step 2: Recall the concept Government has three arms:

• Legislature makes laws, deliberates on policies, and initiates policies through bills.
• Executive implements or enforces laws and public policy.
• Judiciary interprets laws, settles disputes, punishes offenders, protects citizens' rights, and checks the other arms through judicial review.

Step 3: Evaluate each option

• A. Initiating public policy: This is mainly the work of the executive and legislature, so it is not correct.
• B. Deliberating on important policies: This is done by the legislature through debates, so it is not correct.
• C. Checking other arms of government: This is correct. The judiciary can declare actions of the executive or laws of the legislature unconstitutional, null and void. This is called judicial review, and it is a key part of checks and balances.
• D. Implementing public policy: This is the executive's function, so it is not correct.

Step 4: Answer The correct option is C.

Tip: Remember the three arms as Make, Execute, Interpret. Legislature makes laws, executive executes them, and judiciary interprets them and checks the others. When you see "checking," "reviewing," or "interpreting" in a judiciary question, think judiciary.
