The statement "for every action, there is an equal but opposite reaction" is a statement of a. the law of conservation of momentum c. newton's second law b. newton's first law d. newton's third law

Newton's third law of motion.

Step-by-step explanation:

The  statement is given as  "for every action, there is an equal but opposite reaction". This statement is third law of motion. It states that both action and reaction force acts on a single object.

The law of conservation of momentum states that initial momentum is equal to final momentum of an object.          

Newton' first and second law of motion gives the introduction of force and magnitude of force respectively acting on an object.

Hence, the correct option is (d) " Newton's third law ".
