The correct answer is:
B. They cause infections, and can only replicate inside living cells.
Explanation:
Viruses are non-cellular infectious entities because they lack a cellular structure (no nucleus, cytoplasm, or organelles) and are not considered alive outside of a host organism.
They are obligate intracellular parasites, meaning they cannot replicate or carry out metabolic processes outside of a living host cell. Once inside a host cell, they hijack the cell’s machinery to produce more virus particles.
