Which of the following examples illustrates the Law of Multiple Proportions?

$1 \, L$ of $N_2$ combines with $3 \, L$ of $H_2$ to form $2 \, L$ of $NH_3$ under the same conditions. This illustrates the:

Define the Law of Multiple Proportions.

$n \ g$ of substance $X$ reacts with $m \ g$ of substance $Y$ to form $p \ g$ of substance $R$ and $q \ g$ of substance $S$. This reaction can be represented as,$X + Y \rightarrow R + S$. The relation which can be established in the amounts of the reactants and the products will be

The following data are obtained when dinitrogen and dioxygen react together to form different compounds:

Mass of dinitrogen	Mass of dioxygen
$14 \ g$	$16 \ g$
$14 \ g$	$32 \ g$
$28 \ g$	$32 \ g$
$28 \ g$	$80 \ g$
