The modern periodic table arrangement is a result of all of the following except many scientists who contributed individual knowledge. total rejection of the early versions for modern ideas. much scientific reexamination and argumentation of ideas. periodic repetition of the chemical and physical properties of the elements.

The correct option is this: TOTAL REJECTION OF THE EARLY VERSIONS FOR MODERN IDEAS.
The modern periodic table arrangement was as a result of many contributions from many scientists, who contributed individual knowledge. The periodic table has gone through a lot of reexamination and it is always regularly updated as new scientific facts emerge. The elements in the periodic table are arranged based on the periodic occurrence of the chemical and physical properties of the elements.
