Which of the following examples is not correctly matched ?

Options

A. (A)Two most abundant elements -Fe, Al.
B. (B)Two metals which occur in native state -Au, Pt.
C. (C)Two metals which can occur in combined and native state both -Zn, Fe
D. (D)None of these

Explanation

To determine which of the following examples is not correctly matched, we will analyze each option provided:

1. **Option A: Two most abundant elements are Fe and Al.**
- This statement is correct. Aluminum (Al) is indeed one of the most abundant elements in the Earth's crust, and Iron (Fe) is also abundant, though not as much as aluminum. Therefore, this option is correctly matched.

2. **Option B: Two metals which occur in native state are Au and Pt.**
- This statement is also correct. Gold (Au) and Platinum (Pt) are both noble metals that do not readily react with oxygen or sulfur, allowing them to occur in their native state. Thus, this option is correctly matched.

3. **Option C: Two metals which can occur in combined state and native state are Zn and Fe.**
- This statement is incorrect. While Zinc (Zn) can occur in a combined state, Iron (Fe) primarily occurs in a combined state (e.g., in ores like hematite and magnetite) and does not typically exist in a native state. The correct example of a metal that can exist in both states is Copper (Cu), which can be found in its native form as well as in combined forms (e.g., in ores like chalcopyrite). Therefore, this option is not correctly matched.

4. **Conclusion:**
- The option that is not correctly matched is **Option C**.

### Final Answer:
The option that is not correctly matched is **Option C**.
