1. **Understanding the Definition of Inferior Planets**: Inferior planets are those that orbit closer to the Sun than Earth does. This means their orbits are located inside the Earth's orbit.

2. **Identifying the Inferior Planets**: The two planets that are classified as inferior planets are Mercury and Venus. Both of these planets have orbits that are situated between the Sun and Earth.

3. **Analyzing the Options**:
- Option A: "Farthest from the Sun in orbits outside that of Sun" - This is incorrect because inferior planets are not farthest from the Sun; they are closer.
- Option B: "In orbits inner to that of Sun" - This is misleading; it suggests a misunderstanding of the term "inner."
- Option C: "In orbit inner to that of Earth" - This is the correct option, as it accurately describes the position of Mercury and Venus relative to Earth.

4. **Conclusion**: Based on the definitions and the analysis of the options, the correct answer is that inferior planets are in orbits inner to that of Earth.

**Final Answer**: Inferior planets are in orbit inner to that of Earth.
