(D) The first ionization energy values for the group $11$ elements are: $Cu$ $(745 \ kJ \ mol^{-1})$,$Ag$ $(731 \ kJ \ mol^{-1})$,and $Au$ $(890 \ kJ \ mol^{-1})$.Comparing these values:$1$. From $Cu$ to $Ag$,the ionization energy decreases $(745 \rightarrow 731)$.$2$. From $Ag$ to $Au$,the ionization energy increases significantly $(731 \rightarrow 890)$ due to the poor shielding effect of $4f$ electrons (Lanthanoid contraction).$3$. From $Au$ to $Cu$,the ionization energy decreases $(890 \rightarrow 745)$.Therefore,the correct diagram shows a decrease from $Cu$ to $Ag$,an increase from $Ag$ to $Au$,and a decrease from $Au$ to $Cu$.
