Obtaining and keeping a driver's license is considered a:

Obtaining and keeping a driver's license is viewed as a privilege because it is granted by the state and comes with certain responsibilities and requirements that a driver must fulfill. Unlike a right, which is something that is guaranteed to all individuals, driving is regulated and can be denied or revoked based on a person's behavior or adherence to laws.

The privilege of driving implies that it can be taken away if a driver does not comply with traffic laws, engages in reckless behavior, or fails to meet the necessary qualifications, such as passing a driving test or maintaining proper insurance. This reflects the idea that driving is not an automatic entitlement but rather a conditional permission that comes with the responsibility to adhere to safety regulations and laws.

In contrast, the other options suggest a different nature of driving. A requirement typically refers to something that must be fulfilled to participate in an activity, while a burden implies something that is heavy or difficult to carry, which does not capture the essence of holding a driver’s license. Thus, the characterization of a driver's license as a privilege emphasizes the conditional and regulated nature of driving.
