Which organism possesses the highest number of chromosomes?

Ploidy level is $NOT$ same in . . . . . . .

Match the following columns regarding the chromosome number in meiocytes $(2n)$ of different organisms:
| Column-$I$ (Organism) | Column-$II$ (Chromosome number in meiocyte) |
| :--- | :--- |
| $p$. Ophioglossum | $v$. $20$ |
| $q$. Apple | $w$. $34$ |
| $r$. Rice | $x$. $24$ |
| $s$. Maize | $y$. $42$ |
| | $z$. $1260$ |

Match the following columns:

Column-$I$ (Organisms)	Column-$II$ (Chromosome number in meiocytes)
$P$. Housefly	$I$. $38$
$Q$. Rat	$II$. $42$
$R$. Dog	$III$. $12$
$S$. Cat	$IV$. $78$
$T$. Fruit fly	$V$. $8$

Choose the correct option with respect to the following structures:

Structure	Cellular structure	Flagella	Wall
$(a)$ Zoospore	Unicellular	Present	Absent
$(b)$ Conidia	Unicellular	Absent	Present
$(c)$ Gamete	Unicellular	Can be present	Can be present

$A$ : Continued self-pollination checks inbreeding depression.
$R$ : Pollen release and stigma receptivity are synchronised.
