(A): DNA and protein
(B): The case for proteins appeared stronger until the 1940s, especially since biochemists had identified them as a class of macromolecules with great heterogeneity and function specificity, essential requirements for the hereditary material.

(C): Virulent strains are pathogenic (causing disease), whereas non-virulent strains are non-pathogenic (harmless) strains.
