Best Answer Explained in Below-:

The sentence "Hospitals ___ the sick." requires a verb that accurately describes the primary function of hospitals in relation to their patients. The correct answer is "B) treat".

Hospitals are healthcare institutions designed to provide medical care, and their main role is to treat patients who are ill or injured. The term "treat" encompasses a wide range of activities including diagnosis, medical intervention, and ongoing care, which are fundamental to the purpose of a hospital.

While "operate" (option A) is relevant, it specifically refers to surgical procedures and does not capture the full range of care provided by hospitals. "Admit" (option C) refers to the process of accepting patients into the hospital, but does not convey the comprehensive work done after admission. Finally, "nurse" (option D) suggests a role performed by healthcare professionals rather than the institution itself.

In conclusion, "treat" is the most fitting choice because it reflects the holistic approach hospitals take in caring for the sick, making it the best answer for the given sentence.
