Final answer:
Race classification in South Africa during apartheid was a strict and discriminatory system based on physical appearance and heritage. People could not change their race category, but a pencil test was used for hair texture categorization. Colored people could not be labeled as Indian, and one could not be demoted to a lower race.
Step-by-step explanation:
During apartheid in South Africa, race classification was a strict and discriminatory system that divided the population into different racial categories based on physical appearance and heritage. In this system, people were not allowed to fill out an application to move to another race category, so statement A is NOT true.
Statement B is true. A pencil test was indeed used to determine the texture of a person's hair when applying to be classified as white.
Statement C is also true. Colored people, who were classified as a separate racial group, could not be labeled as Indian in the apartheid system.
However, statement D is NOT true. While a person's racial classification could be changed through marriage or adoption, there was no provision for a person to be demoted to a lower race on the apartheid hierarchy scale.
