Step by step solution

01

Step :1  Explanation Incorrect answer (b), (c) and (d)

As a result, choices b, c, and d are erroneous.

In order to generate new viruses, they must first infiltrate and utilize the reproductive system of live cells; only then will they be able to gather the materials needed for reproduction. All life forms have a basic biological, architectural, and economic system called the cell. Viruses, on the other hand, are not formed up of cells.

02

Step :2  Explanation Correct answer (a)

Viruses are microscopic contagious organisms that only replicate inside bacteria living.

Viruses do not have cell nuclei and replicate inside their hosts, however they are not thought about moving for these reasons. These aren't the criteria that biologists employ to determine whether or not this is alive. Virology are also composed of RNA and DNA.
