Can someone tell me the answer and plz no wrong answers

D, a tool too organize the elements

Explanation:

If it were a list, it would be unorganized and not in atomic number or by mass. So A is wrong. It isn't a method to name elements, they are named by their founders who made the discoveries so B and C are both wrong. D must be correct because they are organized in a manner where they are by mass, atomic number, and into their respective groups (alkali metals, alkali earth metals, transition metals, lanthanides, actinides, poor metals, semi metals, non-metals, and noble gases)
