B Correct answer
Explanation

Earth's escape velocity is approximately 25000 miles per hour (about 11.2 km/s). This is the minimum speed needed for an object to break free from Earth's gravitational pull without further propulsion. At this speed, an object can overcome Earth's gravity and escape into space, which is why spacecraft need to achieve this velocity for orbital missions or interplanetary travel.
