Final answer:
The retention period for individuals younger than 18 years is typically 5 years. The correct option is (A).
Step-by-step explanation:
The retention period for individuals younger than 18 years is typically 5 years. This means that certain information or records involving individuals under 18 are retained for a period of 5 years before they are no longer required to be kept.
For example, if a record pertains to a student's academic performance or behavior, it may be kept for 5 years after the student turns 18. This helps ensure that important information is available for future reference if needed.
Therefore, option A, 5 years, is the correct answer.
