Final answer:
A learner's permit application form can be obtained online through the state's website and at the Department of Motor Vehicles (DMV). The National Voter Registration Act of 1993 also allows voter registration to occur when applying for or renewing a driver's license.
Step-by-step explanation:
Application forms for a learner's permit are typically available through several channels. However, the correct answer to where one can get an application form to apply for a learner's permit is: a) Online through the state's website, and c) Only at the Department of Motor Vehicles (DMV).
Some states also allow you to apply when you're at the DMV for other services, like when applying for or renewing a driver's license, as per the National Voter Registration Act of 1993 ("the Motor Voter Act"). Moreover, the Motor Voter Act requires states to offer voter registration at all offices that provide public assistance and at state-funded programs that assist persons with disabilities.
This means that when eligible citizens apply for certain services, they also have the opportunity to register to vote. This integration aims to make the process of voter registration more accessible and convenient for a greater number of people.
