Answer 2

Answer is option "a"

Explanation:

• Virus is the microorganisms which have properties of living and non-living both. They have a specific structure which consists of head and tail. Head is composed of several protein units known as capsomeres which enclose the genetic material made up of RNA or DNA.
• They have a lipid envelope derived from the host cell membrane which lies outside the capsomere. They occur in crystalline form outside the body of the host but as it enters the host cell it injects its genetic material which replicates vigorously.
• The replicated materials are further packed in the new protein coat formed using host protein and is thrown out by the lysis of cell membrane.
• Hence, the right answer is option a "viruses".
