Solution

According to Bohr-Bury scheme, the maximum number of electrons present in a shell is given by the formula $2 n^{2}$ , where ‘n’ is the orbit number.
Therefore, the K shell (n=1) will have a maximum of 2 electrons and the L shell (n=2) will have a maximum of 8 electrons.

In representation (i), K-shell has 2 electrons and L-shell has 5 electrons.
So, it is a correct representation with respect to Bohr-Bury scheme.

In representation (ii), K-shell has 2 electrons and L-shell has 7 electrons.
So, it is a correct representation with respect to Bohr-Bury scheme.

In representation (iii), K-shell has 4 electrons and L-shell has 8 electrons.
So, it is not a correct representation with respect to Bohr-Bury scheme.

In representation (iv), K-shell has 2 electrons and L-shell has 9 electrons.
So, it is not a correct representation with respect to Bohr-Bury scheme.
