$Li, Na, K$ form a Dobereiner's triad. If the atomic masses of $Li$ and $K$ are $7$ and $39$ respectively,what will be the atomic mass of $Na$?

Match the following and select the correct option.

List-$I$	List-$II$
$(1)$ Lothar Meyer	$(A)$ First to present a periodic table showing correct arrangement up to Calcium.
$(2)$ $A$.$E$.$B$. de Chancourtois	$(B)$ Arranged elements in horizontal and vertical rows based on atomic weight.
$(3)$ Newlands	$(C)$ Discovered the element with atomic number $101$.
$(4)$ Seaborg	$(D)$ Suggested that arrangement based on atomic weight is an important concept in the periodic table.
	$(E)$ Presented the first possible periodic table.
	$(F)$ Arranged elements into groups of three.
	$(G)$ Law of Octaves.

What is the periodic table according to Glenn $T$. Seaborg?

The modern periodic table is based on the atomic number of the elements. The experiment which proved the significance of the atomic number was:

The modern periodic table,based on the experiment of atomic number which highlights the significance of atomic number,is associated with:

Given below are two statements :
Statement $(I):$ According to the Law of Octaves,the elements were arranged in the increasing order of their atomic number.
Statement $(II) :$ Meyer observed a periodically repeated pattern upon plotting physical properties of certain elements against their respective atomic numbers.
In the light of the above statements,choose the correct answer from the options given below :
