What is physical fitness?
A) the improvement of the body through intentional movement
B) the speed at which the body moves during exercise
C) the ability of the body to function efficiently during exercise
D) the performance of muscles for long periods of time
I'm pretty sure its going to be A. because, in physical fitness you are improving your health and improving different parts of your body including muscles, heart, etc... and your are improving all of that through intentional movement.
