Correct Option: A. Nine years Detailed Explanation: The Arthur Richards Constitution was introduced in Nigeria in 1946 and was named after Sir Arthur Richards, who was the Governor of Nigeria at the time. This constitution was significant because it marked a shift in the governance structure of Nigeria, moving towards a more representative form of government.

1. Duration of the Constitution: The Richards Constitution was designed to last for nine years. This was a deliberate decision made by the British colonial authorities, reflecting their approach to governance in Nigeria during that period. The idea was to provide a framework for governance that would allow for some degree of political development while still maintaining colonial control.
2. Context of the Constitution: The Richards Constitution was introduced in a time when there was increasing pressure for political reform in Nigeria. The constitution aimed to address some of the demands for greater representation and participation in governance by introducing a legislative council that included elected representatives. However, it still retained significant powers for the colonial government.
3. Significance of the Nine-Year Duration: The nine-year duration was significant because it was intended to provide a stable period for the implementation of the new governance structure. It allowed for a trial period during which the effectiveness of the constitution could be assessed. After this period, the British government could evaluate the political landscape and decide on further reforms or changes.

Why Other Options Are Incorrect:

• B. Five years: This option is incorrect because the Richards Constitution was explicitly designed to last for nine years, not five. A five-year duration would not have provided sufficient time for the intended reforms to take root and be evaluated.
• C. Twelve years: This option is also incorrect. A twelve-year duration would have extended beyond the intended timeframe for the Richards Constitution. The British colonial authorities were cautious about extending the duration too long, as they wanted to maintain control and assess the political situation periodically.
• D. Six years: Similar to the previous options, a six-year duration does not align with the historical context of the Richards Constitution. The decision to set the duration at nine years was based on the need for a balanced approach to governance and reform.

Summary of Key Points:

• The Arthur Richards Constitution was designed to last for nine years.
• It aimed to introduce a more representative governance structure in Nigeria while maintaining colonial control.
• The nine-year duration allowed for a trial period to assess the effectiveness of the constitution.
• Other options (five, six, and twelve years) do not reflect the historical context and intentions behind the Richards Constitution.

This thorough understanding of the Arthur Richards Constitution and its intended duration will help you grasp the broader context of Nigeria's political evolution during the colonial period.
