Explanation

To solve the analogy question: "Accident is related to carefulness in the same way as Diseases is related to ..........", we need to identify the relationship between the first pair of words and apply that same relationship to the second pair.

### Step-by-Step Solution:

1. **Identify the Relationship in the First Pair**:
- The first pair is "Accident" and "Carefulness".
- An accident often occurs due to a lack of carefulness. Therefore, carefulness is a preventive measure against accidents.

2. **Identify the Relationship in the Second Pair**:
- The second pair is "Diseases" and the missing term.
- We need to find a term that represents a preventive measure against diseases, similar to how carefulness prevents accidents.

3. **Evaluate the Options**:
- **Option 1: Sanitation** - This refers to cleanliness and hygiene, which are critical in preventing diseases.
- **Option 2: Treatment** - This refers to managing diseases after they occur, not preventing them.
- **Option 3: Medicine** - This is used to treat diseases but does not prevent them.
- **Option 4: Doctor** - A doctor can treat diseases but is not a preventive measure.

4. **Select the Best Option**:
- Since sanitation is directly related to preventing diseases, just as carefulness prevents accidents, the best option is **Sanitation**.

5. **Conclusion**:
- Therefore, the answer to the analogy is: Diseases is related to **Sanitation**.

### Final Answer:
Diseases is related to **Sanitation**.
