What is the correct order with respect to metallic property of $Zr, Cd, Sn, Sr$?

Select the correct order.

On moving down the group,which of the following properties gradually increases?

Given below are two statements:
Statement $I$: The number of pairs among $[Al_2O_3, Cr_2O_3]$, $[Cl_2O_7, Mn_2O_7]$, $[Na_2O, V_2O_3]$ and $[CO, N_2O]$ that contain oxides of same nature (acidic, basic, neutral or amphoteric) is $4$.
Statement $II$: Among $Na_2O, Al_2O_3, CO$ and $Cl_2O_7$, the most basic and acidic oxides are $Na_2O$ and $Cl_2O_7$, respectively.

In the modern periodic table,the acidic nature of oxides:
