The most popular form of government is

Step 1: Analyze the question The question asks which form of government is the most popular, meaning the one most widely practiced and accepted around the world today.

Step 2: Explain the concepts

• Diarchy (dyarchy): Rule by two authorities sharing power. It is rare. An example is the British colonial arrangement in India under the 1919 reforms.
• Totalitarianism: The state controls almost every part of public and private life, with no opposition allowed. Nazi Germany and Stalin's USSR are examples. Few countries practice it today.
• Democracy: Government by the people, directly or through elected representatives. It is based on free elections, rule of law, and respect for citizens' rights. Nigeria, Ghana, the USA, and the UK are examples.
• Fascism: An extreme nationalist, authoritarian system led by a dictator, as in Mussolini's Italy. It is now largely discredited.

Step 3: Solve by elimination

• A is wrong because diarchy is rare and mostly historical.
• B is wrong because totalitarianism is unpopular and found in only a few states.
• D is wrong because fascism is largely discredited and not widely practiced.
• C is correct because democracy is the form most countries have adopted, and it is widely regarded as the most acceptable system. Nigeria has practiced it since 1999 (the Fourth Republic).

Step 4: Answer The correct option is C. democracy.

Tip: In Government questions that ask for the "most popular" or "most acceptable" system, think of the one built on the people's consent, which is democracy. Also remember the keywords: diarchy = two rulers, totalitarianism = total control, fascism = dictator plus extreme nationalism.
