Explanation:

Properties of eka aluminium matches well with Gallium. Option D is the answer.

In 1871, Mendeleev predicted the existence of a yet-undiscovered element and named it eka-aluminium because of its proximity to aluminium in the periodic table. This element is now known as Gallium. Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery white.
