I apologize for the confusion. When a negatively charged plastic rod is touched to a metal sphere, the negative charges will spread out unevenly on the sphere's surface.

A.B.C or D

C. They spread out unevenly.

The negative charges will spread out evenly throughout the metal sphere. This is known as the principle of electrostatic equilibrium.

To understand why this happens, let's break down the process:

1. Initially, the metal sphere is electrically neutral, meaning it has an equal number of positive and negative charges overall.
2. When Jack touches the negatively charged plastic rod to the metal sphere, some of the negative charges from the rod transfer onto the metal sphere. This causes an imbalance of charges, with more negative charges on the metal sphere than positive charges.
3. However, metal is a good conductor of electricity, which means that the charges are free to move within the metal. The negatively charged electrons in the metal will repel each other, causing them to spread out as much as possible.
4. As a result, the negative charges will distribute themselves evenly throughout the metal sphere, spreading out from the point where the rod made contact. This process continues until an electrostatic equilibrium is reached, where the negative charges are uniformly distributed.

Therefore, the correct response is: "They spread out evenly."
