B) There is no acceleration toward the center of the Earth.

The satellite is in a state of free fall toward the Earth, but its forward motion is such that it falls around the Earth rather than into it, maintaining a constant altitude and position relative to the Earth's surface. This is characteristic of any orbit, including geosynchronous orbits.
