Winston added 6ml of chemical for every gallon of water
Larry added 8ml chemical for every 2 gallons of water
This means that 4ml chemical was added to 1 gallon of water
Then we can conclude that
If we compare the amount of chemical added to 1 gallon of water, we will discover that
Winton used more chemical per gallon than Larry because ratio wise, 6:1 is greater than
8:2
Hence, Option A is correct
