1. Analyze the question The question asks which arm of government has adjudication as its main duty. So we need to know what "adjudication" means.

2. Explain the concept Adjudication means judging or settling disputes, that is, hearing cases, deciding who is right or wrong, and giving a binding decision. Under the principle of separation of powers, government functions are divided among three arms:

| Arm of Government | Primary Function | |---|---| | Legislature | Makes laws (law-making) | | Executive | Implements and enforces laws (administration) | | Judiciary | Interprets laws and settles disputes (adjudication) |

3. Step-by-step solution

• A. Legislature: makes laws, so this is not adjudication.
• B. Politics: this is not an arm of government. It is the activity of acquiring and using power, so it is ruled out.
• C. Executive: carries out and enforces laws, so this is not adjudication.
• D. Judiciary: the courts and judges interpret the law, try cases, and settle disputes between individuals, between individuals and the state, or between government bodies. This is adjudication.

4. Answer The correct option is D. judiciary.

5. Exam tip Link each arm of government to a single keyword:

• Legislature → Legislate (make laws)
• Executive → Execute (carry out laws)
• Judiciary → Judge (adjudicate)

If you see "adjudication", "interpretation of laws", or "settling disputes" in a question, think judiciary immediately.
