Explanation:

It is acted upon by a force directed away from the centre of the earth which counter-balances the gravitational pull.

-

Satellite going around the earth in circular orbit is in state of free fall, and its speed is constant. speed depends upon the radius of orbit of satellite.

So Its angular velocity(ω=v×r) is also constant and thus angular momentum mω is also constant.

Apart from gravitational pull of the earth, there is no other force on the satellite. So option C is incorrect.
