C. Statement -1 is True, Statement -2 is False
D. Statement -1 is False, Statement -2 is True

Answer

To analyze the statements provided in the question, we will evaluate each statement step by step.

### Step 1: Understanding Statement 1
**Statement 1:** In summers, the distance of Earth from the Sun is less than one astronomical unit, while in winters, it is more than one astronomical unit.

- The Earth orbits the Sun in an elliptical path, which means that its distance from the Sun varies throughout the year.
- The point in the Earth's orbit where it is closest to the Sun is called **perihelion**, and the point where it is farthest is called **aphelion**.
- Typically, perihelion occurs around early January (winter in the Northern Hemisphere), and aphelion occurs around early July (summer in the Northern Hemisphere).
- Therefore, during summer (around July), the Earth is at its farthest point from the Sun (aphelion), which is greater than one astronomical unit. Conversely, during winter (around January), the Earth is at its closest point to the Sun (perihelion), which is less than one astronomical unit.

**Conclusion for Statement 1:** This statement is **incorrect**.

### Step 2: Understanding Statement 2
**Statement 2:** One astronomical unit is the average distance of Earth from the Sun when the Earth moves in an elliptical orbit.

- The **astronomical unit (AU)** is defined as the average distance from the Earth to the Sun.
- This average distance is approximately **149,597,870.7 kilometers**.
- Since the Earth does indeed move in an elliptical orbit around the Sun, the definition of the astronomical unit as the average distance is accurate.

**Conclusion for Statement 2:** This statement is **correct**.

### Final Conclusion
- **Statement 1** is incorrect.
- **Statement 2** is correct.

Thus, the correct option is that Statement 1 is false and Statement 2 is true.
