Cigarette companies claim that manufacturing both low- and high-nicotine cigarettes allows smokers to choose how much nicotine they want. However, a recent study has shown that the levels of nicotine found in the blood of smokers who smoke one pact of cigarettes per day are identical at the end of a day's worth of smoking, whatever the level of nicotine in the cigarettes they smoke.
Which one of the following, if true, most helps to explain the finding of nicotine study?
A. Blood cannot absorb more nicotine per day than that found in the smoke from a package of the lowest-nicotine cigarettes available.
B. Smokers of the lowest-nicotine cigarettes available generally smoke more cigarettes per day than smokers of high-nicotine cigarettes.
C. Most nicotine is absorded into the blood of a smoker even if it is delivered in smaller quatities.
D. The level of tar in cigarettes is higher in low-nicotine cigarettes than it is in some high-nicotine cigarettes.
E. When taking in nicotine by smoking cigarettes is discontinued, the level of nicotine in the blood decreases steadily.

Clear A.
Blood becomes saturated with nicotine even with the levels in the low-nicotine cigarettes. So whatever the nicotine levels ingested/inhaled, the blood levels remain the same in a day.
