Ok all. The answer is A because if the rod is removed first then any charge the plate has will go through the wire to the ground so C and D are out of the question. Then due to induction, the positive charges come to the top of the plate and the negative charges come to the bottom of the plate. So the plate is postively charged, giving rise to the answer as A
