Vedclass · Answer

(D) communications satellite,specifically a geostationary satellite,must orbit the Earth in the same direction as the Earth's rotation,which is from west to east.For the satellite to appear stationary relative to a point on the Earth's surface,its orbital period must match the Earth's rotational period ($24$ hours) and it must orbit in the equatorial plane.Therefore,it cannot be vertically above any arbitrary place on the Earth; it must be above the equator.Since both statements $(A)$ and $(B)$ are correct,the correct option is $(D)$.

$A$ communications Earth satellite:
