B Correct answer
Explanation

Earth is the densest planet in our solar system with an average density of about 5.51 g/cm³, which is primarily due to its large iron-nickel core. This is significantly higher than other planets: Mercury (5.43 g/cm³) is close but smaller, while gas giants like Jupiter and Neptune have much lower densities due to their gaseous composition.
