Which of the following is correctly explains why viruses are not classified with either prokaryotes and eukaryote organisms

they contain cells that have no life giving function

they have a cell wall and a cell membrane

they are not surrounded by a protein coat

they cannot reproduce outside a host cell

The correct answer is - They cannot reproduce outside a host cell

Viruses are connecting link between living and non-living things. They can be obtained in crystals which is a non-living property. Using energy of the host they can make their own copy. It is a living organism's property. Thus viruses are made of nucleoprotein which can reproduce using energy of the host because they lack their own energy producing system. Therefore, they cannot reproduce outside a host cell.

They cannot reproduce outside a host cell

Explanation:

The last one is the answer, since viruses have DNA but are not alive they cannot be classed as a prokaryotes or eukaryote. Instead they are classed by their shape, structure, and size.
