Researchers have found that when habitual smokers are provided with low-nicotine cigarettes they:
a) smokers commonly report that smoking reduces stress.
b) adult smoking increases with stress.
c) smokers feel much more relaxed than nonsmokers do.
d) smokers report less anxiety if allowed to smoke.

Option 1 is the answer - smoke more to maintain their nicotine intake

Explanation:

Nicotine is a highly addictive component of tobacco that leads to the continuous smoking of cigarette by habitual smokers. When nicotine obsession develops, it becomes very difficult to refrain from the use of tobacco products by addicted individuals.

Experimental studies on reduced nicotine content cigarettes have shown that when chain-smokers are presented with low nicotine cigarettes, they tend to adjust their smoking habits so as to maintain the amount of nicotine intake they need.
