Answer:

A

Explanation:

Usually a virus is mainly made up of genetic material (DNA or RNA) inside a capsid/envelope. It has no organelles like a ‘true’ cell. Because it cannot reproduce on its own, scientists struggle to categorize it as a living thing since  reproduction is a property of living things. The virus reproduces by hijacking the cellular mechanisms of the host cells to replicate itself. It does so by integrating itself in the genome of the host so that its DNA is also replicated, along with that of the host, by the host cell DNA polymerases and its proteins produced by the ribosomes of the host.

Cellular organization is one of the characteristics of life that states that each living organism is made up cell or more than one cell, that is made up by organization of various components such as chemicals like micro molecule that form the macro molecule and these chemical level structural organization is formed together to make cells and this level of organization makes the tissue which is complex to cell but simpler to organ that is makeup of various together.

The makeup of organs is necessary as organs are the structural level that individuals facilitate the function and make up the organ system that is a complex system made up of organs that are similar in their function. The organism is the most complex of all levels.

Thus, the correct answer is option A.
