Concept:This was a diplomatic protest by Nigeria against Britain's refusal to penalise apartheid South Africa.
Explanation:The Commonwealth Games took place in Edinburgh, Scotland, in July
1986.
At that time, South Africa's apartheid regime was widely condemned for racial discrimination.
Many Commonwealth nations, especially Nigeria, called on Britain to impose sanctions on South Africa.
Britain refused to apply such sanctions.
In response, Nigeria withdrew its team from the games.
The boycott demonstrated Nigeria's strong opposition to apartheid.
It also showed Nigeria's willingness to take a firm stand against a fellow Commonwealth member, Britain.
This action is remembered as a key moment in Nigeria's foreign policy under the military government of General Ibrahim Babangida.
Answer:Option A: Failure to impose sanctions on South Africa.
