Which of the following order of acidic strength is correct?

Which of the following is/are amphoteric oxide$(s)$?

$Li$ resembles $Mg$ due to diagonal relationship which is attributed to

Given below are two statements :
Statement $I$ : An element in the extreme left of the periodic table forms acidic oxides.
Statement $II$ : Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table.
In the light of the above statements,choose the correct answer from the options given below :

The electronic configuration of an atom $A$ is $1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^{10}, 4s^2 4p^3$. The chemistry of $A$ is therefore likely to be similar to that of:

The correct order of the metallic character of the elements $Be, Al, Na, K$ is
