b. Feedback response
Explanation:
Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.
A virus is a tiny organism and may lead to mild-severe illnesses in animals or plants or humans.
Biologically we can term virus as a bit of RNA or DNA in a protein coat. It cannot replicate without another organism.
If we use an image of indicator, we may say yes virus is living. This is because the virus particle is non-cellular but has an NDA core.This core is enclosed in a protein coat and it has spike-like projections in all over its surface.
