Explanation:
Detailed explanation-1: -Viruses are classified into four groups based on shape: filamentous, isometric (or icosahedral), enveloped, and head and tail.
Detailed explanation-2: -Shapes of viruses are predominantly of two kinds: rods, or filaments, so called because of the linear array of the nucleic acid and the protein subunits; and spheres, which are actually 20-sided (icosahedral) polygons.
Detailed explanation-3: -Viruses are very diverse. They come in different shapes and structures, have different kinds of genomes, and infect different hosts. Viruses reproduce by infecting their host cells and reprogramming them to become virus-making “factories."
