Which of the following statements about tobacco products is true? a. tobacco products contain over 4,000 different chemicals. b. all chemicals found in tobacco products are carcinogens. c. cigarettes are the least used tobacco product. d. tobacco products are difficult to obtain.

B

Explanation:

For me, the answer is A : Tobacco products contain over 4,000 different chemicals.

Tobacco and tobacco smoke can contain over 4,000 different chemicals. They can be either harmful or cancer-causing (carcinogens), meaning not all of them are cancer-causing. Out of all the 4,000 different chemicals in tobacco and tobacco smoke, only around 60 of the substances cause cancer. Don't get me wrong, that's a lot, but it just shows that the difference in ratio is huge. Cigarettes are one of the most common, if not, the most common used tobacco product. Tobacco is also relatively easy to obtain. Therefore, the answer is A : Tobacco products contain over 4,000 different chemicals.
