D. 393 million hectares.

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the total land area of the world. This requires knowledge of geographical statistics.

2. **Recall the Total Surface Area of Earth**: The total surface area of the Earth is divided into land and water. Approximately one-fourth of the Earth's surface is land.

3. **Convert Surface Area to Hectares**: To find the total land area in hectares, we can use the fact that the total surface area of Earth is about 510 million square kilometers. Since 1 square kilometer equals 100 hectares, we can convert this to hectares.

4. **Calculate Total Land Area**:
- Total surface area of Earth = 510 million km²
- Total land area = 1/4 of 510 million km² = 127.5 million km²
- Convert to hectares: 127.5 million km² × 100 = 12,750 million hectares.

5. **Compare with Given Options**: The options provided are:
- 1393 million hectares
- 13393 million hectares
- 1,03,393 million hectares
- 393 million hectares

6. **Identify the Correct Option**: The closest and correct value to our calculation is 13,393 million hectares.

7. **Conclusion**: Therefore, the total land area of the world is approximately 13,393 million hectares.

**Final Answer**: B. 13,393 million hectares.
