A) perigee speed
B) circular satellite velocity
C) Newtonian orbit velocity
D) the Keplerian speed
E) the speed of sound (or Mach 1)

The minimum speed required to launch an object so that it remains the same distance above the ground and just falls around the Earth is called the circular satellite velocity. This is the speed at which the object's centripetal force balances out the Earth's gravitational force, resulting in a circular orbit. The other options listed are not relevant to this concept.
