**Answer:**

There is no component of force acting along the direction of motion of the satellite.

**Explanation:**

It is given that, a satellite in a circular orbit travel at a constant speed. The acceleration of an object is equal to the rate of change of velocity. At a particular point, the acceleration of the satellite will is equal to 0. We know that force is given by :

F = m a

If a is 0, then the force acting on the satellite is zero. So, there is no component of force acting along the direction of motion of the satellite. **Hence, the correct option is (b).**

Anaerobic means without air so it would be B. Anaerobic
