Answer 1

Answer: (A)

24 h

A geostationary satellite is an earth-orbiting satellite, placed at an altitude nearly $35,800$ kilometers directly above the equator, that revolves in the same direction as the earth rotates (from west to east). The time period of revolution of a geostationary satellite around earth is same as that rotation of earth about its own axis i.e. $24$ hours.
