Most malleable metal is:

Options

A. magnesium
B. gold
C. iron
D. copper

Explanation

**Step-by-Step Solution:**

1. **Understanding Malleability:**
- Malleability is the property of a metal that allows it to be deformed under compressive stress, which means it can be hammered or rolled into thin sheets without breaking.

2. **Identifying the Most Malleable Metal:**
- Among various metals, we need to identify which one has the highest malleability. Common metals include gold, silver, copper, and aluminum.

3. **Researching Malleability of Common Metals:**
- Gold is known for its exceptional malleability. It can be hammered into extremely thin sheets, known as gold leaf, which is used in various applications including art and decoration.
- Silver is also malleable but not to the extent of gold.
- Other metals like copper and aluminum are malleable, but again, they do not surpass gold.

4. **Conclusion:**
- Based on the properties of these metals, gold is recognized as the most malleable metal.

5. **Final Answer:**
- Therefore, the most malleable metal is **Gold**.
