During a Routine Physical Examination, the Health Care Practitioner Mentions

During a routine physical examination, the health care practitioner mentions that an adolescent girl has asymmetrical breasts. The girl is too embarrassed to ask the doctor about this, but she also notices one breast seems bigger than the other. She asks the school nurse: "Why is one of my breasts bigger than the other? What is wrong?" The best response by the nurse is which of the following?

A) "You have not achieved full growth. The smaller breast will eventually grow and they will be the same size."
B) "Many women have asymmetrical breasts. It is not unusual for one breast to be slightly larger."
C) "Don't worry too much about this, as the health care practitioner will surely order a mammogram."
D) "This condition will correct itself after you have experienced menarche."
