Answer:
The correct answer is D. cigarettes .
Explanation:

In a few decades, cigarette consumption became widespread in most western countries, reaching more than 50% of the adult population.
The take-off of this massive consumption of tobacco occurs, in the United States, from the 20s of the 20th century, between the 30s and 40s in Central Europe and from the 50s in Spain. This phenomenon triggered one of the most serious health problems that modern society has faced.
