I believe it is C because that is mostly what ethics is.
Weight of the person last week = 205 pounds
Percentage of weight lost by the person due to dieting = 4%
Amount of weight lost by the person due to dieting = 205 * (4/100) pounds
= 820/100 pounds
= 8.2 pounds
So the amount of weight lost is 8.2 pounds.
I'm pretty certain that the answer is "quickly".
