registration with Selective Service

I have no idea.

None of those.

The last one is close, but it only applies to young men between the ages of 18 and 25.

To find out what the US federal government requires of its male citizens, we need to refer to official sources such as government websites or legal documents. In this case, we can look into the requirements related to military service and Selective Service, which is the system used to draft individuals into the armed forces if necessary.

1. Citizenship before military service: The US federal government requires that individuals be United States citizens in order to join the military or be subject to military service.

2. Volunteer military service: While volunteer military service is an option for both male and female citizens, it is not specifically a requirement for all male citizens.

3. Reserve military service: Reserve military service refers to serving as an active part-time member of the military while maintaining a civilian life. This is not a requirement for all male citizens but is an option for those who choose to serve in the reserves.

4. Employment in Selective Service: There is no requirement for employment in Selective Service specifically. Selective Service administers the process of conscription (draft), but it does not require employment.

5. Mandatory military service: The United States does not currently have mandatory military service, so it is not a requirement for male citizens.

6. Registration with Selective Service: Male citizens in the United States are required by law to register with the Selective Service System within 30 days of their 18th birthday. This requirement applies to most male U.S. citizens and immigrant males residing in the U.S.

Based on the options provided, the correct choices from this list would be:
- Citizenship before military service
- Registration with Selective Service

It's important to note that government requirements can change over time, so always refer to the official sources for the most up-to-date information.
