The correct answer is (c) First law of motion.
Physical independence of forces means that the effect of each force on an object is independent of the presence of other forces. This concept is closely related to Newton's First Law of Motion, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force. This implies that the effect of each force can be considered independently when analyzing the motion of an object, a principle that is fundamental in the study of mechanics and is used in the superposition of forces.
