The answer is D. It is obvious since it is a one-choice question and both A and B state the exact same thing. Therefore the answer has to be D and so C has to be correct as well. Exam techniques! : D

Helena Farrell · Answer 2

D. All of the above. When a wire loop is moved or rotated in a magnetic field, there is a change in magnetic flux which produces emf in wire loop and hence electric current is produced.
