Explanation:

Recently (in October 2021), China was suspected to have tested Fractional Orbital Bombardment System. A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn. The flight path of the warhead from the system does not reveal the target location till the payload hits the destination. Hence option (c) is the correct answer.
