C. It tells the decor of the men
Its the 3 one because apostrophes shows u who it belongs to and the bathroom belong to the men
The correct sentence that uses apostrophes properly is B: "The décor of the men’s room looked like it had not been changed since the 1970s." It correctly shows possession with "men's" and formats the decade as "1970s" without an apostrophe. Options A and C contain errors regarding possession and the use of apostrophes in dates.
