Best answer
Right option is (c) Protein

The explanation: Prior to the works done by Oswald Avery, Colin MacLeod and Maclyn McCarty, the genetic material was thought to be as the protein. Nucleoids are the irregular shaped structures in the prokaryotic cell. They contain nearly all of the genetic material of the prokaryotes. Nucleons are present inside the nucleus of an atom, alongside with the protons. Chromosome carries the genetic information of the genes.
