Options

B. Morphine
C. Heroin
D. LSD

Answer

To solve the question regarding which addictive habit could lead to the danger of urinary bladder, throat, and lung cancer, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which addictive habit is linked to the risk of developing cancer in the urinary bladder, throat, and lungs.

2. **Analyzing Option A - Tar**:
- Tar is a byproduct of burning tobacco. It contains numerous carcinogenic (cancer-causing) compounds.
- Smoking tobacco leads to a higher risk of lung cancer, throat cancer, and has also been linked to urinary bladder cancer due to the way the body processes and excretes the harmful substances found in tobacco.

3. **Analyzing Option B - Morphine**:
- Morphine is a powerful painkiller and an opioid. It is not known to cause cancer in the urinary bladder, throat, or lungs. Its primary use is for pain management, and while it is addictive, it does not have the same carcinogenic properties as tar.

4. **Analyzing Option C - Heroin**:
- Heroin is also an opioid derived from morphine. Like morphine, it is highly addictive and primarily associated with addiction and overdose risks rather than direct links to cancers of the urinary bladder, throat, or lungs.

5. **Analyzing Option D - LSD**:
- LSD (lysergic acid diethylamide) is a hallucinogenic drug. It does not have a known association with causing cancer in the urinary bladder, throat, or lungs. Its effects are primarily psychological rather than physical in terms of cancer risk.

6. **Conclusion**: Based on the analysis, the only option that is associated with an increased risk of urinary bladder, throat, and lung cancer is **Option A - Tar**.

### Final Answer:
The correct answer is **Option A - Tar**.
