Whose resignation in 1941 led to the collapse of Nigeria Youth Movement(NYM)?

Analyze the question: It asks about the event that split the Nigerian Youth Movement (NYM) in 1941, which led to its collapse as a national force.

Background: The NYM was founded in 1934 as the Lagos Youth Movement. It was led by figures such as Herbert Macaulay, H.O. Davies, Ernest Ikoli, Samuel Akinsanya, Dr. J.C. Vaughan and Kofo Abayomi.

In 1938 the NYM won all the Legislative Council seats in Lagos, defeating Macaulay's NNDP. Then came the crisis:

• In 1941, the Lagos Legislative Council seat became vacant after Dr. Kofo Abayomi's resignation (he had represented the NYM).
• The NYM nominated Samuel Akinsanya, but Ernest Ikoli, an Ijaw man and editor of the African Daily Times, was also put forward as a candidate.
• The NYM executive chose Ikoli. Akinsanya contested and the Yoruba members of the NYM saw this as a tribal matter. Ikoli won, and Akinsanya, H.O. Davies and other Yoruba leaders resigned from the NYM.

This ethnic split was the real cause of the NYM's collapse.

Which option fits "whose resignation"? In the standard textbook account (and the question bank), the crisis is traced to the resignation of Dr. Kofo Abayomi from the Legislative Council seat, which triggered the contest between Ikoli and Akinsanya. Other accounts say H.O. Davies and Akinsanya resigned from the NYM as a result of the dispute. These resignations were the consequence, while Abayomi's resignation was the trigger.

Answer: D. Kofo Abayomi

Tip: Remember the chain: Abayomi resigns → Ikoli vs Akinsanya → Yoruba/Ijaw ethnic quarrel → NYM splits. "Abayomi's exit started it."
