Explanation:

To determine the centripetal force keeping a satellite in orbit around Earth, we analyze each option:

• Option A: Tension is a force in strings/ropes, not relevant for satellite orbits.
• Option B: Supporting force acts on objects in contact with a surface, not applicable here.
• Option C: Gravitational force between Earth and the satellite provides the centripetal force required for circular motion (orbit).
• Option D: Friction acts when surfaces slide/roll, not present in space for satellite - Earth interaction.

Answer:

C. Gravitation force
