Final answer:
Persons A and B, born on February 23, 2000 and February 23, 2001 respectively, are both of legal drinking age in the U.S. as of February 23, 2022, and you could legally sell or deliver alcohol to them. Persons C and D are not yet 21 and it would be illegal to provide them with alcohol.
Step-by-step explanation:
To legally sell or deliver alcohol to a person, they must be of legal drinking age. In the United States, the legal drinking age is 21 years old. If today is February 23, 2022, we calculate whether the individuals born on the given dates have turned 21 years old.
Accordingly, you could legally sell or deliver alcohol to persons A and B, as they have both reached the legal drinking age of 21. Persons C and D are not yet 21, therefore it would be illegal to sell or deliver alcohol to them on this date.
