The correct option is A. John Newlands was an English scientist, in 1864 he organized all the known elements in order of their relative increase of atomic mass. After doing this, he realized that some of the elements have similar characteristics and properties. In 1869, Mendeleev, who was a Russian scientist published the periodic table. He also organized the elements based on their increasing atomic mass, but he also went further and organize items in such a way that elements with similar properties fall in the same column.
