Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
