Which of the following is an example of why voter registration laws exist?

A. To ensure that only citizens of a specific country can vote

B. To guarantee that all eligible individuals have the opportunity to vote
C. To restrict certain groups of people from voting
D. To create barriers and discourage voter participation

Both A and B can be considered as reasons why voter registration laws exist. However, B is a more accurate response as it focuses on the purpose of voter registration laws, which is to ensure that all eligible individuals have the opportunity to vote. Voter registration laws allow for the verification of an individual's eligibility to vote and can help prevent voter fraud. The purpose is not to restrict certain groups or create barriers to voter participation.
