"Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell".

Answer:
d.Primary Succession
Explanation:
ECOLOGICAL SUCCESSION is the series of changes that a particular ecosystem undergoes over a particular period of time. Ecological succession can be of two types viz: primary succession and secondary succession.
Primary succession is a type of ecological succession that involves the colonization of a barren area of land with no soil i.e. no pre-existing organisms. The barren area consists of bare rocks and surfaces that are colonized by organisms like LICHENS for the first time. These organisms are called PIONEER.
The lichens act on the bare rocks by secreting chemicals that help degrade the rock particles to form soil, which paves way for other organisms like plants to grow.
