Registration for Selective Service occurs at which age range?

Registration for Selective Service is required for all males in the United States when they reach the age of 18. The law mandates that individuals register by the time they turn 18 years old, and they must do so by the time they reach 26 years old. This means the registration window properly encompasses ages 18 to 26, making this the correct choice.

The registration process is a part of the federal laws that ensures the government maintains a list of individuals who are available to serve in the armed forces in the event of a national emergency. It is crucial for civics and governmental operations, highlighting the responsibilities of citizenship.

Other age ranges mentioned do not fit the established legal requirements. The first option suggests a range that starts too early, while the last two options extend beyond the maximum age limit set by the law. Understanding this specific age requirement is essential for grasping the responsibilities that come with citizenship in the U.S.
