What is the minimum age to apply for a California driver's permit?

Answer: B — 15

Other options such as A, C, and D are incorrect because they do not align with the minimum age requirement set by the state of California to apply for a driver's permit. According to the California Department of Motor Vehicles, the minimum age to apply for a permit is 15 years and 6 months. This age requirement allows individuals to complete the necessary driver education and training before applying for a permit. Therefore, the minimum age to apply for a California driver's permit is 15 years and not any younger.
