<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A scientist performed an experiment to produce hybrid viruses by mixing two different serotypes of influenza virus, H1N1 and H2N2, in a respiratory epithelium cell line. Several days later, the scientist collected the media and analyzed the viral progeny. She found the following serotypes of virus: H1N1, H2N2, H1N2, and H2N1. Which of the following terms best explains the appearance of new serotypes?? A: Recombination, B: Reassortment, C: Complementation, D: Phenotypic mixing, E: Transformation,  <response>: This question is asking about the mechanism that led to the appearance of new influenza serotypes H1N2 and H2N1 when two parental serotypes H1N1 and H2N2 were mixed together. The key is to understand how influenza viruses exchange genetic material to generate new strains.Choice A Recombination refers to genetic exchange between similar viruses by crossing over during replication. This does not apply here since the parental viruses are different serotypes. Choice B Reassortment refers to exchange of gene segments when two different influenza viruses coinfect the same cell. This allows new combinations of genes to be packaged into viral progeny. This is the correct mechanism to explain the appearance of the novel H1N2 and H2N1 serotypes.Choice C Complementation involves two viruses with defects cooperating to perform essential viral functions. This does not explain generating new serotypes. Choice D Phenotypic mixing is the temporary acquisition of surface proteins from another virus. This is transient and does not generate stable new serotypes.Choice E Transformation involves transfer of genetic material between cells, not between viruses.B: Reassortment
