Explanation:

Question 4 (Multiple Choice)

Smokeless tobacco (like chew, snuff) has high sugar and acid content (causing tooth decay), contains carcinogens (linked to mouth, esophageal, pancreatic cancers), and nicotine (which is addictive). So all listed effects (tooth decay, cancers, addiction) occur.

E - cig explosions happen due to battery malfunctions, leading to burns, broken teeth from debris, and even death in severe cases. So the statement is true.

Scientific evidence on e - cigs as a quit - aid is mixed. Many studies show limited or no clear proof they help most people quit long - term, and some have risks. So the claim that they’ve been “scientifically proven” to help quit is false.

Answer:

D. All of the above
