Solution

The correct option is A Gallium and germanium
Mendeleev predicted the properties of Eka-aluminium and Eka-silicon which were unknown at that time to fill the gaps under aluminium and silicon in the periodic table. Later, when these elements were discovered, their properties were found to be similar to those predicted by Mendeleev and were later named as gallium and germanium respectively.
