The reaction occurs as follows:

2 \mathrm{C}_{2} \mathrm{H}_{6}+7 \mathrm{O}_{2}\: \rightarrow \: 4 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O}

Molar Mass of Ethane = 30 g/mole.
Molar mass of water = 18 g/mole.

From the Equation,

? 2 x 30 grams of Ethane produces 6 x 18 grams of Water.
∴ 1 gram of the Ethane produces (9/5) grams of Water.
∴ 6 grams of Ethane produces 10.8 grams of Water.


Now, Using the Formula,
 No. of Moles of Water = Mass/Molar Mass
 = 10.8/18
 = 0.6 moles.

Therefore, Option(3) is correct.
