so the answer is c

The correct answer is C. Allowed white voters to avoid discriminatory laws

Explanation:

In the legislature, the term "grandfather clause" is used when there is a new law or similar, but instead of applying to all the population the legislature allows some part of it to continue with the old law or rule, making an exempt in the legislature. This was first applied during the 19th century as there were changes in the Constitutions that asked the population to pay poll taxes, take literacy text and other restriction in order to vote. However, these new requirements did not apply to all the population but exceptions were made in some states for those that ancestors with the right to vote, which means some people could avoid the new discriminatory laws for voting. Thus, a grandfather clause was a law that "allowed white voters to avoid discriminatory laws".
