hospitalization ______ A. 住院治疗 B. 医院 C. 医院的

hospitalization ______ A. 住院治疗 B. 医院 C. 医院的

The correct answer is:

A. 住院治疗 (hospitalization treatment)

This refers specifically to the act or process of being hospitalized or receiving medical treatment in a hospital.

B. 医院 means "hospital."

C. 医院的 means "hospital's" or "of the hospital," which isn't the right fit in this context.
