The pathway that would lead to activation of cytotoxic T cells includes body cell that becomes infected with new virus entry.

What is the role of Cytotoxins in the entry of a new viruses?

Cells can die in one of two ways.

Physical or chemical damage causes cell disintegration or necrosis.

  • One such example is the lack of oxygen in the cardiac muscle during a heart attack or the damage produced by antibodies and complements.
  • Phagocytic cells collect and destroy dead or necrotic tissue, cleaning the wounded tissue and repairing the lesion gradually.
  • The other form of cell death is apoptosis or intentional cell death.
  • Apoptosis is a normal cellular response that is essential for tissue remodelling throughout development and metamorphosis in all multicellular animals.

Hence, the correct answer is option B
