Final answer:
A leather name tag for a uniform should contain the full name and rank of the individual. Social Security numbers are not included for security reasons, and other details like unit name or medical information are not standard for name tags.
Step-by-step explanation:
The information that should typically be on a leather name tag for a uniform is A) Full name and rank. This type of identification helps in verifying the individual's identity and their position or authority within a structured organization such as the military or police. Personal information like a Social Security number should never be included due to security risks. Instead, name tags maintain essential, non-sensitive information for straightforward identification purposes.
