Two electrically neutral metal spheres, A and B, on insulating stands are placed in contact with each other. A negatively charged rod is brought near, but does not touch the spheres, as shown in the diagram below. How are the spheres now charged?

• A is positive and B is positive.
• A is negative and B is positive.
• A is positive and B is negative.
• A is negative and B is negative.
