Final answer:
Late bloomers refer to individuals who experience a delay in the typical progression of romantic development. Option b is the false statement as it does not accurately define late bloomers.
Step-by-step explanation:
The false statement about late bloomers is option b. Late bloomers include 14- to 16-year-olds who say they have not had a romantic relationship. Late bloomers generally refer to individuals who experience a delay in the typical progression of romantic development. This could include 17- to 19-year-olds who have not had a romantic relationship that has lasted more than 4 months (option a) or who have had no experience in romantic relationships (option c). Late bloomers fall outside the typical timeline of romantic development (option d).
