Concept:Nelson Mandela’s 28-year imprisonment was a direct result of his lifelong fight against apartheid — a system of racial segregation and discrimination in South Africa.
Explanation:Mandela actively opposed the apartheid regime and its laws that separated people by race.
He led protests and refused to stop his struggle for equality.
As a result, the government imprisoned him for 28 years, along with thousands of other black and coloured people.
His imprisonment was not a punishment for a common crime; it was a political act to silence his voice against racial injustice.
Option B wrongly suggests it was just a punishment for an offence, ignoring the political context.
Option C is incorrect because Mandela did not seek power through imprisonment; he suffered for his beliefs.
Option D is wrong because South Africa did not have a king or monarchy at that time — the enemy was the apartheid government, not a royal family.
Thus, the true reason for his long imprisonment was his determined opposition to apartheid and his fight to end segregation policies.
Answer:Option A: for opposing apartheid and struggle against policies of segregation.
