Newton's third law is the real law of motion. Reason (R): The first and the second law are contained in the 3rd law.
Newtons second law is said to be the real law of motion since its generates the Equation of Motion of any particle and is quite appreciably the only law which can govern all the physics. From the first and second law we get the 3rd Law.
So the reason can be correct as we get from 1st and 2nd law but the assertion is wrong.
I hope this answer helps. All the very best for your future endeavors!
