Explanation:

🆕 New Concept Discovered: Health Risks of Smokeless Tobacco
Understanding how non-smoked tobacco products affect the body.

Step 1: Analyze option (a)

Spit tobacco (smokeless tobacco, such as chewing tobacco or snuff) contains nicotine, which is absorbed through the mouth tissues directly into the bloodstream. It is highly addictive, making this statement false.

Step 2: Analyze option (b)

While spit tobacco significantly increases the risk of cheek and gum cancers, stating a specific, universal multiplier like "exactly 10 times" is statistically inaccurate and not a standard general medical fact.

Step 3: Analyze option (c)

Respiratory injuries are primarily associated with inhaled tobacco products (like cigarettes or vapes) that affect the lungs, rather than spit tobacco which is kept in the mouth.

Step 4: Analyze option (d)

Because spit tobacco is held directly against the gums and oral cavity lining, it exposes these tissues to high concentrations of carcinogens. This direct contact is strongly and undeniably linked to an increased risk of oral cancers (including cancers of the mouth, tongue, cheek, and gums). This statement is true.

Answer:

d) It carries an increased risk of oral cancer.
