B) He was seen in the Emergency Department.
C) He was seen in the emergency department.
My answer is B

Right.

The correct answer is C no capitalization of emergency department. Got B wrong

Correct! The sentence "He was seen in the Emergency Department" is the correctly capitalized sentence. When referring to a specific department or unit, such as the Emergency Department in this case, the first letter of each main word should be capitalized.
