Which of the following options shows the correct correlation between column $I$,$II$,and $III$?

Column $I$	Column $II$	Column $III$
$A$. Calcium	$I$. Required for ionic balance	$(i)$. Grey blot on leaves
$B$. Boron	$II$. Essential for constitution of nucleic acid	$(ii)$. Fruit-yield decreases
$C$. Phosphorus	$III$. Required for absorption of calcium	$(iii)$. Red blot on leaves
$D$. Chlorine	$IV$. Required to activate respiratory enzyme	$(iv)$. Fruit-size diminishes
$E$. Manganese	$V$. Required for synthesis of mitotic spindle	$(v)$. Young root tip begin to die

Identify the correct pair:

Column-$I$	Column-$II$
$P$. Phosphorus	$I$. Splitting of water to liberate oxygen during photosynthesis
$Q$. Potassium	$II$. Constituent of cell membranes and all nucleotides
$R$. Magnesium	$III$. In more abundant quantities in the meristematic tissue,buds,leaves,and root tips
$S$. Manganese	$IV$. Constituent of the ring structure of chlorophyll and helps to maintain the ribosome structure

$P - Q - R - S$
