The two correct answers that use an apostrophe correctly in a plural possessive noun are:
- The basketball players’ lockers will be cleaned out on Friday.
- The United States’ national anthem is “The Star-Spangled Banner.”
The first sentence indicates that multiple players possess the lockers, making it correctly a plural possessive. The second sentence correctly indicates that the national anthem belongs to the United States, which is also treated as a singular entity in this context.
The other sentences either misuse the apostrophe or apply it incorrectly based on singular/plural distinctions.
