Which of the following is NOT a type of engineering?

The correct answer indicates that Medical Engineering is not traditionally recognized as a distinct field like the other options listed. Aerospace, Environmental, and Computer Engineering are well-established branches of engineering that are widely acknowledged within engineering curricula and professional practice. Aerospace Engineering focuses on the design and development of aircraft and spacecraft, Environmental Engineering deals with the application of engineering principles to improve and protect the environment, and Computer Engineering merges electrical engineering and computer science to develop computer systems and hardware.

While the field of medical technology does exist and often overlaps with engineering disciplines, it is typically classified under Biomedical Engineering, which encompasses the application of engineering principles to the medical field. Thus, while Medical Engineering may be informally referenced in some contexts, it lacks the formal recognition and established curriculum associated with the other engineering disciplines listed.
