Select ALL statements about tobacco smoke components that are supported by the material.

### Why this is right - **A** is supported: nicotine is described as addictive and as affecting the nervous system. - **B** is supported: tar is associated with lung-tissue damage and cancer. - **C** is supported: carbon monoxide reduces oxygen transport in the blood. ### The concept Cigarette smoke contains thousands of chemicals. The material names three components to show that smoke can have different effects: addiction and nervous-system effects, tissue damage and cancer risk, and reduced oxygen transport. These are examples, not a complete list of smoke chemicals. ### The other options - **D. Passive smoke contains none of the harmful components found in smoke inhaled by active smokers.** This is false because passive smokers inhale many of the same harmful components. ### Terms - **Nicotine**: An addictive smoke component that affects the nervous system. - **Tar**: A smoke mixture associated with lung-tissue damage and cancer. - **Carbon monoxide**: A harmful gas that reduces oxygen transport in the blood. ### Remember Match each named smoke component to its stated effect rather than treating all effects as interchangeable.
