Antigens are usually proteins, peptides (amino acid chains) and polysaccharides (chains of monosaccharides/simple sugars) but lipids and nucleic acids become antigens only when combined with proteins and polysaccharides.
Cytopathic effects are changes in host cells due to viral infections. Thus, the correct option is A.
<h3>What are Cytopathic effects?</h3>
Cytopathic effects may be defined as the process of structural transformations in a host cell resulting from viral infection.
Cytopathic effects happen when the infecting virus provokes lysis of the host cell or when the cell perishes without the process of lysis because of its ineptitude to reproduce.
As a result, this virus causes morphological transformations in the host cell is known as cytopathogenic.
Therefore, the correct option for this question is A.
