Detailed explanation-1: -Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid.

Detailed explanation-2: -Because they can’t reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they’re very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.

Detailed explanation-3: -Viruses do not have cells. They have a protein coat that protects their genetic material (either DNA or RNA). But they do not have a cell membrane or other organelles (for example, ribosomes or mitochondria) that cells have. Living things reproduce.

Detailed explanation-4: -Viruses are not cells: they are not capable of self-replication and are not considered “alive”. Viruses do not have the ability to replicate their own genes, to synthesise all their proteins or to replicate on their own; thus, they need to parasitise the cells of other life-forms to do so.

Detailed explanation-5: -Antibiotics do not acts against virus as they are made up of polymorphic protein coat. Viruses have different type of symmetry like icosahedral and helical. So, the correct answer is option B.
