Elsa has recently experienced fatigue, weight change, hair loss, nausea, loss of sexual interest, sleep problems, and loss of appetite after her treatment for cancer. These symptoms are most likely to follow​

A) ​chemotherapy.
B) ​surgery.
C) ​hormonal treatment.
D) ​immunotherapy.

The symptoms described are commonly associated with the side effects of chemotherapy. The nausea, hair loss, and fatigue are well-known effects of chemotherapy, while the weight loss, sleep problems, and loss of appetite can also be due to treatment-induced changes in metabolism and hormonal levels. Additionally, loss of sexual interest is a known side effect of certain chemotherapy drugs. Surgery may cause some of these symptoms, but not to the same extent or duration as chemotherapy. Hormonal treatment and immunotherapy may cause their own sets of side effects but do not typically produce these symptoms.
