Metal which is found in its native state?

Options

A. Pt
B. Cu
C. Fe
D. Ag

Explanation

To solve the question "Metal which is found in its native state?", we will analyze the options provided and determine which metals are typically found in their native or free state in nature.

### Step-by-Step Solution:

1. **Understand the Concept of Native State**:
- The native state refers to the natural occurrence of metals in their pure form, uncombined with other elements. Metals that are found in their native state are generally less reactive.

2. **Analyze the Options**:
- **Option A: Platinum**: Platinum is a noble metal and is found in its native state due to its low reactivity.
- **Option B: Copper**: Copper is also a coinage metal and is found in its native state because it is relatively unreactive.
- **Option C: Iron**: Iron is more reactive compared to the above metals and is typically found in nature in the form of oxides, sulfides, or carbonates, not in its native state.
- **Option D: Silver**: Silver is another coinage metal and is found in its native state due to its low reactivity.

3. **Conclusion**:
- Based on the analysis, the metals that are found in their native state are **Platinum (A)**, **Copper (B)**, and **Silver (D)**. Iron (C) does not qualify as it is found in a combined state.

### Final Answer:
The metals which are found in their native state are **Platinum, Copper, and Silver**.
