D. Sodium (Na) and Florine (F)
The answer is Al and Ga
This is because Al (aluminum) and GA (gallium) are in the same row in the periodic table, unlike the other answers. This makes them have the MOST physical and chemical properties in common.
PS. if you find yourself with an answer with multiple pairs of elements that are in the same row, the answer will be the ones that are closest to each other.
Alluminum and Gallium
