(d) None of the above

Options

A. Baldness
B. Yellowing of eyes
C. Lung cancer
D. None of the above

Answer

To determine the harmful effect of smoking from the given options, we can analyze each option step by step.

### Step 1: Analyze Option (a) Baldness
- Baldness is primarily influenced by genetic factors, hormonal changes, and aging. While smoking may contribute to overall health deterioration, it is not directly linked to causing baldness. Therefore, this option is not a harmful effect of smoking.

**Hint:** Consider the primary causes of baldness and whether smoking is a direct factor.

### Step 2: Analyze Option (b) Yellowing of Eyes
- Yellowing of the eyes, also known as jaundice, can occur due to liver issues or other medical conditions. Although smoking can affect overall health, it is not a direct cause of yellowing of the eyes. Thus, this option is also not a harmful effect of smoking.

**Hint:** Think about the medical conditions that lead to yellowing of the eyes and their relation to smoking.

### Step 3: Analyze Option (c) Lung Cancer
- Lung cancer is a well-documented and significant harmful effect of smoking. Cigarette smoke contains carcinogens, which are substances that can lead to cancer. When inhaled, these carcinogens damage lung tissue and can lead to the development of lung cancer over time. This option is a direct harmful effect of smoking.

**Hint:** Recall the relationship between carcinogens in cigarette smoke and the development of cancer.

### Step 4: Analyze Option (d) None of the above
- This option suggests that none of the previous options are harmful effects of smoking. However, since we have established that lung cancer is a harmful effect, this option is incorrect.

**Hint:** Consider whether any of the previous options are indeed harmful effects of smoking.

### Conclusion
Based on the analysis, the correct answer is **(c) Lung cancer**, as it is a well-known harmful effect of smoking.

**Final Answer:** (c) Lung cancer
