$R$. Escherichia coli	$III$. $3.3 \times 10^9 \, bp$
$S$. Human haploid $DNA$	$IV$. $4.6 \times 10^6 \, bp$

What types of nitrogenous bases are present in $DNA$ and $RNA$ respectively?

$S$ Statement: $DNA$ is inherited by organisms produced by parents.
$R$ Reason: $DNA$ acts as a gene.
$(a)$ Both $S$ and $R$ are true,and $R$ is the correct explanation of $S$.
$(b)$ Both $S$ and $R$ are true,but $R$ is not the correct explanation of $S$.
$(c)$ $S$ is true and $R$ is false.
$(d)$ $S$ is false and $R$ is true.
$(e)$ Both $S$ and $R$ are false.
