Correct answer: D. Ba
- A. Li
- B. K
- C. Ca
- D. Ba
- E. Rb
Explanation
Down the group, the density of the elements increases, and Group II elements have a higher density than Group I elements because of their higher mass and lesser volumes. Ba is the only group II in all the options above.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
