In international relations, states have a right to

Step 1: Analyze the question The question asks about a right states have in international relations, meaning a right that arises in dealings between states, not one that concerns purely internal matters.

Step 2: Explain the concept Under international law, states have rights such as sovereignty, independence, equality, self-defence, and legation (the right to send and receive diplomats). The right of legation is backed by the Vienna Convention on Diplomatic Relations (1961). It gives diplomats and envoys immunity from arrest and from the jurisdiction of the host state's courts.

Step 3: Evaluate each option

• A. Create more states and local governments: This is an internal, domestic matter, not international relations.
• B. Diplomatic immunity of their envoys: This is a right recognised internationally. A state's diplomats are protected when they serve in other countries. ✔
• C. Establish formidable armed force: This is mostly a domestic defence matter, and it is limited by treaties and arms-control agreements.
• D. Mine their mineral resources: This is an internal economic matter, an aspect of sovereignty over natural resources.
• E. Withdraw from bilateral agreement: A treaty cannot simply be abandoned. Withdrawal must follow the terms of the treaty or the law of treaties, so it is not an unrestricted right.

Step 4: Answer Diplomatic immunity is the only option that arises directly from relations between states and is firmly established in international law.

Tip: When a question says "in international relations", look for the option that involves other states, such as diplomats, treaties, or recognition. Options about internal matters (creating states, mining, local governments) are usually distractors.
