Whose political framework laid the foundation for the establishment of 19% constitution of Nigeria?

Analyzing the question: The question says "19% constitution", which is clearly a typo for a constitution with a year like 19__. We need to find which governor's political framework laid the foundation for it.

Key facts on the colonial constitutions of Nigeria:

• 1922 Clifford Constitution - Sir Hugh Clifford
• 1946 Richards Constitution - Sir Arthur Richards
• 1951 Macpherson Constitution - Sir John Macpherson
• 1954 Lyttleton Constitution - Oliver Lyttleton
• 1960 Independence Constitution
• 1963 Republican Constitution

Other governors:

• Bernard Bourdillon (Governor 1935-1943): He is known for dividing Nigeria's Southern Provinces into the Western and Eastern regions in the early 1940s and for proposing changes to the constitution, which prepared the ground for later reforms. Richards followed him and then introduced the 1946 constitution.
• Donald Cameron (Governor 1931-1935): Known for Indirect Rule reforms in Tanganyika and Nigeria.
• James Robertson (Governor-General 1955-1960): Associated with the 1960 independence arrangements.

Working it out: The wording "political framework laid the foundation for" a constitution suggests the earlier governor's ideas became the base for the later document. Bourdillon's 1939 regional restructuring (creating the Eastern and Western provinces, giving Nigeria three regions with the North) laid the groundwork for the regionalism that the 1946 Richards Constitution formalized by introducing regional legislative houses. Richards Constitution's regional structure grew out of Bourdillon's framework.

I should be honest about the ambiguity: the question is badly typed, and the missing year makes this uncertain. If the year were 1946, many textbooks would say the answer is Richards himself (A). But the question asks whose framework laid the foundation, which points to the predecessor, Bourdillon.

Answer: B. Bernard Bourdillon

Exam tip: Memorize the chain of governors and constitutions in order: Clifford (1922) → Bourdillon (1939 regional division) → Richards (1946) → Macpherson (1951) → Lyttleton (1954). When a question says "laid the foundation for," think of the person right before the named constitution.
