Step 1: Analyze the question The question asks for the first inter-territorial political movement of the 1920s. It linked the British West African territories (Gold Coast, Nigeria, Sierra Leone, and The Gambia) in the struggle against colonial rule.

Step 2: Explain the concept "Inter-territorial" means the organization operated across several colonies, not just one. In the early 20th century, most nationalist groups were local. The first to unite educated elites across British West Africa was the National Congress of British West Africa (NCBWA).

Step 3: Examine the options

• A. Aborigines Right Protection Society (ARPS): Founded in 1897 in the Gold Coast to protest land alienation. It was local, not inter-territorial, and it predates the 1920s.
• B. West African Youth League: Founded in 1934 by I.T.A. Wallace-Johnson in the Gold Coast and later active in Sierra Leone. It came in the 1930s, not the 1920s.
• C. National Congress of British West Africa: Founded in 1920 in Accra by J.E. Casely Hayford of the Gold Coast. It had delegates from the Gold Coast, Nigeria, Sierra Leone, and The Gambia. It demanded elected representation in the legislative councils, and it was the first movement to unite the British colonies in this way.
• D. West African Students Union (WASU): Founded in London in 1925 by Ladipo Solanke. It was a student organization abroad, and it was not the first such inter-territorial political movement.

Step 4: Answer

Tip: Remember the key words "1920, Casely Hayford, Accra, four British colonies" for NCBWA. Also, "ARPS = land (1897)", "WASU = students in London (1925)", and "WAYL = 1930s, Wallace-Johnson."
