(C) For element $P$,the large jump between $IE_1$ $(495.8)$ and $IE_2$ $(4562)$ indicates it has $1$ valence electron,identifying it as an alkali metal.For element $Q$,the large jump between $IE_2$ $(1451)$ and $IE_3$ $(7733)$ indicates it has $2$ valence electrons,identifying it as an alkaline earth metal.For element $R$,the jumps between $IE_1, IE_2,$ and $IE_3$ are relatively small,suggesting it has $3$ valence electrons (e.g.,Aluminum),making it a $p-block$ element.Since $P, Q,$ and $R$ represent elements with $1, 2,$ and $3$ valence electrons respectively,they are likely in the same period (e.g.,$Na, Mg, Al$).Thus,the statement '$R$: $s-block$ element' is incorrect.

Element	$IE_1$	$IE_2$	$IE_3$
$P$	$495.8$	$4562$	$6910$
$Q$	$737.7$	$1451$	$7733$
$R$	$577.5$	$1817$	$2745$

The first three ionisation energies (in $kJ/mol$) of three representative elements are given below:
