An organised group of citizens acting together and seeking to obtain the control of government is a

Step 1: Analyze the question

The question describes a group with three key features:

1. It is organised (it has structure and leadership).
2. Its members are citizens acting together.
3. Its main aim is to obtain control of government.

Step 2: Explain the concept

A political party is an organised group of people who share similar political ideas and come together to win elections and form or control the government. This is what separates it from other groups in society. Pressure groups and civil society organisations try to influence government, but they do not normally seek to control it.

Step 3: Evaluate each option

• A. Civil society: This is a broad term for non-governmental organisations, community groups and associations that operate between the citizen and the state. They monitor and influence government but do not seek to govern.
• B. Labour union: This protects the interests of workers, such as wages and working conditions (e.g. NLC, ASUU). It is a pressure group and does not aim to take over government.
• C. Student union: This represents students' welfare and interests (e.g. NANS). It is also a pressure group.
• D. Political party: Its main objective is to win power through elections and run the government (e.g. APC, PDP, LP in Nigeria). This matches the description exactly.

Step 4: Answer

The correct option is D. political party.

Exam tip: Remember the difference this way: pressure groups influence government, political parties seek to control it. If a question mentions "contesting elections" or "seeking to control government", think political party.
