Final answer:
The UDF and COSATU played significant roles during the mass resistance against apartheid in South Africa.
Step-by-step explanation:
The UDF (United Democratic Front) and COSATU (Congress of South African Trade Unions) played significant roles during the mass resistance against apartheid in South Africa.
The UDF was an anti-apartheid coalition formed in 1983, bringing together various political, social, and labor organizations. It organized protests, boycotts, and acts of civil disobedience, aiming to challenge and dismantle the apartheid system.
COSATU, founded in 1985, was a trade union federation that played a crucial role in the resistance. It organized strikes and worker mobilization, using its economic power to put pressure on the apartheid government and advocate for workers' rights and social justice.
