Answer

To solve the question "Circular shadow of Earth on the Moon occurs during:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Eclipses**:
- There are two main types of eclipses: solar and lunar. A solar eclipse occurs when the Moon is between the Earth and the Sun, while a lunar eclipse occurs when the Earth is between the Sun and the Moon.

2. **Identify the Relevant Eclipse**:
- The question asks about the shadow of the Earth on the Moon. This situation occurs when the Earth blocks sunlight from reaching the Moon, which is characteristic of a lunar eclipse.

3. **Visualize the Positions**:
- In a lunar eclipse, the Earth is positioned directly between the Sun and the Moon. The sunlight is blocked by the Earth, creating a shadow that falls on the Moon.

4. **Eliminate Incorrect Options**:
- **Solar Eclipse**: This occurs when the Moon is between the Earth and the Sun, so this option is incorrect.
- **Sunrise and Sunset**: These are daily occurrences related to the rotation of the Earth and do not involve the alignment of the Earth, Moon, and Sun. Thus, these options are also incorrect.

5. **Conclude with the Correct Answer**:
- Since the circular shadow of the Earth falls on the Moon during a lunar eclipse, the correct answer to the question is **A) Lunar Eclipse**.

### Final Answer:
The circular shadow of the Earth on the Moon occurs during a **lunar eclipse**.
