B Correct answer
Explanation

Respiratory syncytial virus (RSV) was first isolated in 1956 by Morris and co-workers who named it “chimpanzee coryza agent”. Shortly thereafter, Chanock and co-workers confirmed that the agent was able to cause respiratory illness in humans. Respiratory syncytial virus measures from 121 to 300 nm. It has an RNA genome, and like all members of the paramyxovirus family, the envelop exhibits spokes of glycoprotein.
