Solution

The correct option is D Dmitri Mendeleev and Lothar Meyer
The periodic table of today owes its development to two chemists namely the Russian chemist Dmitri Mendeleev and the German chemist J. Lother Meyer. In 1869, they independently proposed that when the elements are arranged in the increasing order of their atomic weights, similarities in physical and chemical properties appear at regular intervals.
