Answer: A. Equal opportunities for people of all ethnicities.
Step-by-step explanation:
Self-determination refers to the right that people should have to determine their future or destiny instead of being disenfranchised such that their opportunities are limited thereby forcing them into certain roles.
The Civil Rights era was all about seeking the right to self-determination through equal rights for all. They believed that equal rights would lead to equal opportunities which would allow minority groups to decide what they want to be without being limited to certain fields alone.
