Answer:
B. Fact
Explanation:
Forget the idea that the filter is an optional and decorative element of the cigarette, giving it a more uniform appearance. Above all, the filter aims at the health of its users. In industrialized models, for example, it appeared in the mid-1950s, when the first medical studies pointed out the harmful effects of cigarette smoking.
The idea is, basically, to make the filter absorb more nicotine and tar with each drag, and, consequently, the user inhale more air and less smoke in this process. But what became a relief from the damage caused by cigarette smoking has become an environmental issue afterwards.
With this we can affirm that it is a fact that the filters protect against the adverse health effects of the use of nicotine.
