All the answers that apply are :

A. Viruses  must replicate inside a cell

B.  cannot survive without a host

D.  are bundles of genetic material in a protein casing

Explanation:

In biology, a virus can be described as an infectious agent or particle that need a host cell for its survival or reproduction.

Virus incorporate themselves into the host DNA and make copies of themselves. In this way, they reproduce. For example, bacteriophage is a virus that infects the bacterial cells and uses the machinery of the bacterial cell for growth.

The viruses are very tiny and usually are just made up of the genetic material enclosed by a protein casing.
