A full driving license can be valid for which of the following time periods?

A full driving license is typically valid for time periods that align with established regulations and standards for road safety and driver accountability. Choice B, which states that a full driving license can be valid for 5 or 10 years, aligns with common practices in many regions where licenses are often issued for these durations.

The 5-year term is often used for certain types of licenses or situations where more frequent renewals may be required. On the other hand, a 10-year license may be provided as an option for experienced drivers, encouraging compliance with longer-term validity while still requiring periodic renewals to ensure that the driver maintains necessary safety standards and addresses any changes in personal circumstances that could affect driving ability.

In contrast, the other time periods listed do not usually correspond with established licensing policies in most jurisdictions. This makes option B the correct choice based on general licensing practices.
