(C) The cell cycle consists of $G_{1}$,$S$,$G_{2}$,and $M$ phases.$1$. In the $G_{1}$ phase (Gap $1$),the cell grows and synthesizes $RNAs$ and proteins required for $DNA$ replication.$2$. In the $S$ phase (Synthesis),$DNA$ replication occurs.$3$. In the $G_{2}$ phase (Gap $2$),the cell synthesizes proteins (such as tubulin) necessary for spindle fiber formation and prepares for mitosis.Therefore,$A$ is $G_{1}$ phase and $B$ is $G_{2}$ phase.

Mix Examples-Cell Cycle and Cell Division

$A$ cell at the telophase stage is observed by a student in a plant brought from the field. He tells his teacher that this cell is not like other cells at the telophase stage. There is no formation of a cell plate,and thus the cell contains a higher number of chromosomes compared to other dividing cells. This would result in:

$S -$ Statement: Cells cannot maintain their efficient size through mitosis.
$R -$ Reason: Meiosis is an important process for evolution.

$A$: In telophase,the two daughter nuclei formed at opposite poles contain the same number of chromosomes as the parent nucleus.
$R$: In anaphase,the centromere of each chromosome splits,allowing the sister chromatids to separate.
