Solution

The correct option is D $\frac{7}{2}$
Reaction of the process:
$2 C_{2} H_{6} + 7 O_{2} \to 4 C O_{2} + 6 H_{2} O$

We can see in a reaction for the complete combustion of 7 molecules of oxygen is required for 2 moles of ethane.

So for combustion of one molecule of ethane -oxygen is required $= 7 / 2$
