Solution

The correct option is A $B > L i > K$
Ionization Energy: It is a energy required to remove an electron from a gaseous atom or ion.
Trend:
Ionization energy decrease down the group.
Ionization energy increases from left to right.
$L i$ and $K$ are present in the same group of periodic table whereas $L i$ and $B$ are present in the same period of the periodic table.
Thus, the correct order of the ionization potential is $B > L i > K$
