Which of the following has very high $I{P}_2$

Given:- It is given to find which of the option has very high $I{P}_2$.

Explanation:-

As there in $Zn$ the outermost electronic configuration after second ionization potential it becomes $3d$complete fully filled orbital. 
But in case of $Cu$ outermost electronic configuration after first $IP$ it becomes $3d$ complete more stable. Now removal of electron from a fully filled stable orbital is difficult. 

Therefore, correct answer is 3) $Cu$.
