D. 0.41

Explanation

To answer the question "What portion of the moon is visible from the Earth's surface?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Moon's Visibility**: When we observe the Moon from Earth, we do not see the entire surface of the Moon. This is due to the Moon's rotation and its orbit around the Earth.

2. **Percentage of Visibility**: Research and observations indicate that approximately 57% to 59% of the Moon's surface is visible from Earth at any given time. This means that we only see a little more than half of the Moon.

3. **Reason for Partial Visibility**: The Moon does not emit its own light; instead, it reflects sunlight. The portion of the Moon that is illuminated by the Sun is what we can see from Earth. The rest of the Moon, which is not illuminated, remains hidden from our view.

4. **Conclusion**: Therefore, the portion of the Moon that is visible from the Earth's surface is about 57% to 59%.

### Final Answer:
The portion of the Moon visible from the Earth's surface is approximately 57% to 59%.
