B) Replication
C) Information
D) Variation

The fact that the type R and S strains of Streptococcus pneumoniae had small differences in capsule structure shows variation, which is a key criterion for genetic material. The differences in capsule structure were responsible for the differences in virulence and transformability between the two strains. Transmission, replication, and information are other key criteria for genetic material, but they are not directly relevant to this specific observation about the different strains.
