Solution

The correct option is C Both I and II
Escape velocity is the minimum speed needed for an object to escape from a massive body, in the sense of becoming neither on the surface nor in closed orbit of any radius no matter how great, without the aid of thrust, or suffering the resistance from friction. The escape velocity from Earth is about $11.186$ km/s $(6.951$ mi/s; $40, 270$ km/h; $25, 020$ mph $)$ at the surface.
