a. a moving magnetic field creates an electric field.
b. a constant magnetic field creates an electric field.
c. a constant electric field creates a magnetic field.
d. a moving electric field creates a magnetic field

Answer : A. A moving magnetic field creates an electric field

D. A moving electric field creates a magnetic field

Explanation :  

A. A moving magnetic field creates an electric field because when we move a magnet toward the coil then the emf induced in the coil that means the current induced in the coil and the induction shows the electric field .

D. A moving electric field creates a magnetic field because when charge moving or electric current passes through a conducting wire then, create the magnetic field around the wire.
