Solution

The correct option is C The assertion is true, but the reason is false.
$2 H_{2} + O_{2} \to 2 H_{2} O$
In this reaction, 2 moles of hydrogen react with 1 mole of oxygen to form 2 moles of water.
Similarly, 4 moles of hydrogen react with 2 moles of oxygen to form 4 moles of water.
Since the reactants are present in stoichiometric ratios, there are no limiting reagents.
