The Lederberg experiment, also known as replica plating, demonstrates that bacterial resistance to viruses (phages) arises through random mutations rather than being induced by the phages. In this experiment, only a fraction of the original colonies would be resistant to a phage like T1, as shown in option A, where 150 out of 1500 colonies are resistant, indicating pre-existing mutations rather than adaptation or induction by the phage.
