B Correct answer
Explanation

Dmitri Ivanovich Mendeleev is credited with developing the Periodic Law in 1869, which states that chemical properties of elements are a periodic function of their atomic masses. He created the first periodic table and even predicted the existence and properties of elements that had not yet been discovered. Niels Bohr developed atomic structure theory, Huygens studied wave optics, and Newton formulated classical mechanics.
