14

There are two sets 16G1 gallons and 8G2 gallons details given.
16 gallons covering 224 miles
Then 1 G1 is used to cover 14 miles.
Now for 8 G2 covering 224 miles.
then 1 G2 is used to cover 28 miles.
There must 28 - 14 = 14 miles per gallon increment is needed for 8 gallons to improve the mileage to cover 224 miles.
IMO C is correct answer.
