The correct option is C A parabola
If a vehicle reaches escape velocity with respect to the sun it will leave the solar system entirely and take up a trajectory in interstellar space. Starting from the surface of the Earth, a launch velocity of about 54,000 feet per second will lead to escape from the solar system The course of the vehicle will be a parabola, with the Sun at its focus; until eons later it is deflected by some star or other body.
