The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state. The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle. This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle; some cell types (such as neurons and heart muscle cells) when they reach maturity (that is, when they are terminally differentiated) become post-mitotic (enter the G0 phase), and perform their main functions for the rest of the life of the organism. Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.
I believe the correct answer from the choices listed above is option B. Aging effects all of the body's cells; and therefore, the basic building blocks of tissues. As your body ages, many tissues lose mass resulting in atrophy. <span>Organ </span>Atrophy<span> is a decrease in the tissue mass of an organ due to either a decrease in size of individual cells (cellular </span>atrophy<span>). Hope this answers the question.</span>
