Solution

The correct option is A The satellite's distance from the Earth is decreasing
Orbital speed of the satellite v=GMr where G,M are constants.
v1r
Thus increase in speed of the satellite will decrease the radius of the circular orbit in which the satellite is orbiting.
Hence option B is correct.
