  • C The velocity at which a rocket travels through space ✔ ✖
  • D The velocity at which a rocket burns out ✔ ✖
Correct Answer: Option A

Explanation

The escape velocity is the minimum speed an object needs to achieve to escape the gravitational pull of a massive body, such as the Earth. In the case of a rocket leaving the Earth's atmosphere, it needs to reach the escape velocity in order to overcome the gravitational pull of the Earth and leave the atmosphere.
