According to the case history, Mrs.Wharton is a 59-year-old woman who presented in the dermatologist's office with a complaint of changes in a mole or a nevus.

Explanation:

The correct answer to complete the sentence is the term "nevus". A nevus (plural:nevi) is the medical term for the word mole, which in most occasions is what patients will use to describe the condition. A nevus or mole are the product of a collection of colored cells, and are very common among people, with the average of 10 to 40 nevi per person. Although most nevus are harmless in their nature, it is important for everyone that has one to check them regularly, and in the case that the person sees a change in the appearance of the nevus he/she should go to the doctor's office for a medical examination, just like Mrs. Wharton did.

the correct answer is 2 and 4
