D

Step 1: According to Faraday's law of electromagnetic induction, a changing magnetic field within a closed loop induces an electromotive force (emf) in the loop.
Step 2: When the north pole of the magnet approaches coil A, it creates a changing magnetic field in coil A. This induces a current in coil A.
Step 3: The induced current in coil A will flow in a direction that opposes the increase in magnetic flux due to the approaching north pole (Lenz's Law). Thus, it will flow in a clockwise direction when viewed from the left.
Step 4: As the magnet continues moving to the right, the magnetic flux linked with coil B starts to change as well. A similar effect will occur in coil B as the south pole moves towards it, inducing a current in coil B as the magnet moves.
Step 5: The induced current in coil B will oppose the decrease in magnetic flux, causing it to flow in a counterclockwise direction when viewed from the left.
Therefore, the induced currents in A and B are in opposite directions.
Thus, the correct answer is D.
