In which type of cell division are chromosomes not clearly visible?

The phases of the cell cycle are given below. Which of the following options correctly identifies the phase represented by the labels?

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Tetrad	$(P)$ Zygotene stage
$(2)$ Chiasmata	$(Q)$ Diplotene stage
$(3)$ Splitting of centromere	$(R)$ Meiosis
$(4)$ Bivalent	$(S)$ Pachytene stage
	$(T)$ Anaphase
	$(U)$ Mitosis

Match the following:

Column-$I$	Column-$II$
$A$. $G_2$-phase	$1$. First phase of prophase-$I$
$B$. Anaphase	$2$. Proteins are synthesized in preparation for mitosis
$C$. Leptotene	$3$. Terminalisation of chiasmata
$D$. Diakinesis	$4$. Centromeres split and chromatids separate

Statement $X$: During the process of meiosis,the genetic material replicates only once.
Statement $Y$: During interkinesis,there is no replication of genetic material.

$Assertion (S)$: Every newly formed cell follows the cell cycle.
$Reason (R)$: Plant cells lack centrioles.
