B Correct answer
Explanation

Orbiting spacecraft are in continuous free fall toward Earth, but their forward velocity prevents them from hitting the ground - they keep missing it as they fall. This creates the apparent weightlessness. Microgravity is the result, not the cause. Frictionless glide is incorrect in atmosphere; counter thrust is meaningless.
