Statement $Y$: During interkinesis,there is no replication of genetic material.

Which of the following statements is incorrect?

Match the following columns and select the correct option:

Column-$I$	Column-$II$
$(1)$ $G_1$-phase	$(a)$ Interval between $DNA$ replication and $M$-phase
$(2)$ $G_2$-phase	$(b)$ Interval between $G_2$ and $G_1$ phase
$(3)$ $S$-phase	$(c)$ Interval between $M$ and $DNA$ replication
$(4)$ $M$-phase	$(d)$ Interval between the beginning and end of interphase

Meiosis and mitosis differ from each other because in meiosis

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