Solution

The correct option is B Statement-1 is True, Statement-2 is True; Statement-2 is not a correct explanation for Statement-1
Statement-1: Hydrogen is inflammable and combustible gas. Hydrogen undergoes combustion in air or oxygen giving water by an exothermic reaction. $2 H_{2} + O_{2} \to 2 H_{2} O + 485 k J$
Statement-2: It burns with blue flame in $O_{2}$ but does not support burning.
On taking a burning candle in a jar of hydrogen gas, it extinguishes but the gas burns giving a blue flame. This shows hydrogen itself is combustible but does not support in combustion.
Hence, Statement-1 is True, Statement-2 is True; Statement-2 is not a correct explanation for Statement-1
