Look at the image, and read the excerpt from "Black Hole Beginnings." Ribbons of gas swirling off the surface of a star.

In the star's center, the gas is so energized that it has become a sort of super gas, called plasma. The hot plasma is in constant motion. It expands like hot air inside a balloon and pushes outward from the center.

Which statement correctly explains how the image and text work together to support understanding?

The image shows what the center of a star looks like, and the text describes how hot it is.
The image shows what the sun looks like, and the text compares it to a hot-air balloon.
The image shows the movement of plasma from a star, and the text explains why it moves.
The image shows the expansion of a balloon, and the text explains what causes it to expand.
