Solution

The correct option is C
$2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (I)$

Explantion for correct answer:
Option (c): $2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (I)$
During the formation of Water both Hydrogen( $H$ ) and Oxygen( $O$ ) are in gaseous form and produce Water in liquid form.
The reaction proceeds as follows:
$2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (I)$
The preceding process shows the synthesis of Water from Hydrogen and Oxygen gas.
Two moles of Hydrogen in the gaseous state react with one mole of Oxygen in the gaseous state to form two moles of Water in the liquid state in this reaction.
As a result, the right answer is option (c).
