A Correct answer
Explanation

One gene-one enzyme theory was proposed by Beadle and Tatum. Coupling and Repulsion phenomenon in genetics was explained by Bateson and Punnett. Transduction in bacteria was discovered by Lederberg and Zinder. The semi-conservative method of DNA replication was demonstrated by Watson and Crick (with Meselson and Stahl's experimental verification). Option A correctly matches these.
