A-, B-S, C-.

Post reproductive stage of a cell includes cell growth. The term cell growth is used in the contexts of cell development and cell division. As we are concerned about growth (development) only, it refers to the growth of cell that is to increase in cytoplasmic and organelle volume that is in -phase

S-phase is the sub-phase between -phase and -phase, during which DNA synthesis or replication takes place.

In animal cells, during the S-phase, DNA replication begins in the nucleus and the centriole duplication in the cytoplasm. The amount of DNA per cell doubles in the nucleus. If the initial amount of DNA is denoted as 2C, then it increases to 4C. However, there is no increase in the chromosome number
