Which of the following has most density

Options

A. Fe
B. Cu
C. B
D. Pb

Explanation

To determine which of the given elements has the highest density, we will compare the densities of each element provided in the question.

### Step-by-Step Solution:

1. **List the Densities**:
- Iron (Fe): 7.874 g/cm³
- Copper (Cu): 8.96 g/cm³
- Boron (B): 2.34 g/cm³
- Lead (Pb): 11.29 g/cm³

2. **Compare the Densities**:
- Compare the density of Iron (7.874 g/cm³) with Copper (8.96 g/cm³):
- Copper is denser than Iron.
- Compare the density of Copper (8.96 g/cm³) with Boron (2.34 g/cm³):
- Copper is denser than Boron.
- Compare the density of Boron (2.34 g/cm³) with Lead (11.29 g/cm³):
- Lead is denser than Boron.
- Finally, compare the density of Lead (11.29 g/cm³) with Iron and Copper:
- Lead is denser than both Iron and Copper.

3. **Conclusion**:
- After comparing all the densities, we find that Lead (Pb) has the highest density at 11.29 g/cm³.

### Final Answer:
- The element with the highest density among the given options is **Lead (Pb)**.
