Complete the sentence with the most appropriate word or phrase out of the given options.
She was sitting next to the ____ care unit of the hospital.

intensive

The most appropriate word to complete the sentence is intensive.

The other options are not as accurate. Emergency suggests that the care unit is for patients who are in immediate danger, but this is not necessarily the case. Extensive suggests that the care unit is very large, but this is also not necessarily the case. General suggests that the care unit is for all types of patients, but this is not the case. Intensive is the best option because it suggests that the care unit is for patients who require close monitoring and specialized care.
