(A) Orbit Earth over the poles. FALSE

(B) Orbit Earth at a distance where the magnitude of the centrifugal force is zero. FALSE

(C) Are stationary over a fixed point on Earth. TRUE

(D) Only monitor stationary weather systems. FALSE

(E) Are positioned at an altitude of 360 kilometers above Earth’s surface. FALSE, THEY ARE MUCH HIGHER

C. The "stationary" part of the word should clue you in.

So are you willing take the answer people give you here for gospel, put it in your homework, but what have you learned? How do you know the answers you get here are correct? Some people will deliberately give you wrong answers just to make you look like a fool.

Here is another point to consider. How do you know your teacher is not monitoring this and other Q&A sites like this one to catch cheaters?

None of your Answers are true: Geostationary Satellites orbit the Earth at an Altitude where their speed of orbit matches the speed of the Earth's rotation and they APPEAR to be Stationary over one position. A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level

Geostationary satellites are commonly used for Satellite TV. You point the dish at one point in space, because the dish has to point directly at the satellite at all times. They orbit over the equator at an altitude of about 36,000 km.

Low Earth Orbit (LEO) satellites and the Space Station orbit the Earth in about 90 minutes at bout 360 km altitude.
