Solution
The correct option is C Lederberg and Lederberg
In 1952, Esther and Joshua Lederberg performed an experiment that helped to show that many mutations are random, not directed. With their experiment, they showed that antibiotic-resistant strains of bacteria surviving an application of antibiotics had the resistance before their exposure to the antibiotics, not as a result of the exposure. Their experiment showed how adaptations are already present at the genetic level and not produced due to the conditions in which the organism needs to adapt. So, the correct answer is 'Lederberg and Lederberg'
