Answer:
D). Newton's First Law of Motion
Explanation:
This is the explanation of Newton's First law or Law of inertia.
As per this law if there is no unbalanced force on a system then they system will always maintain its state of motion.
Or in other words we can say that if there is no force then the object will always maintain its state of motion i.e. if object is in motion then it will continue in motion and if object is in rest then it will continue at rest
So here when bike immediately stops then due to this law our body will continue its state and move off from the bike and fly away on the ground at some distance away.
So here correct answer will be
D). Newton's First Law of Motion
