D Correct answer
Explanation

Dmitri Mendeleev created the first successful periodic table in 1869, arranging elements by atomic weight and leaving gaps for undiscovered elements. His predictions about missing elements proved correct. Lavoisier categorized elements but didn't create a periodic table. Newlands proposed the Law of Octaves. Kekulé is famous for work on organic chemistry structure, not periodic tables.
