Which of the following element is found in its native state:-

Options

A. Sodium
B. Gold
C. Silver
D. Both (B) and (C)

Explanation

To determine which of the given elements is found in its native state, we need to understand what "native state" means in the context of metallurgy. The native state refers to the elemental form of metals that are found in nature, typically as uncombined metals. These metals are usually less reactive and are often referred to as noble metals.

### Step-by-Step Solution:

1. **Understand Native State**:
- Native state means the elemental form of metals that exist naturally without being combined with other elements.
- Less reactive metals tend to be found in their native state.

2. **Identify Less Reactive Metals**:
- Noble metals are examples of less reactive metals. These include gold (Au), silver (Ag), and platinum (Pt).
- These metals do not easily react with other elements and are often found in their pure form.

3. **Evaluate the Given Options**:
- Let's analyze the options provided:
- **Option A: Sodium (Na)** - Sodium is an alkaline metal and is highly reactive. It is not found in its native state but rather in compounds.
- **Option B: Gold (Au)** - Gold is a noble metal and is found in its native state.
- **Option C: Silver (Ag)** - Silver is also a noble metal and is found in its native state.
- **Option D: Both B and C** - This option suggests that both gold and silver are found in their native state.

4. **Conclusion**:
- Since sodium is highly reactive and not found in its native state, while both gold and silver are noble metals found in their native state, the correct answer is **Option D: Both B and C**.

### Final Answer:
The elements found in their native state are **Gold (Au)** and **Silver (Ag)**, hence the answer is **Option D: Both B and C**.
