Solution

The correct option is D the effect of lanthanide contraction
Atomic size of gold is almost the same as that of silver. It is due to the effect of lanthanide contraction.

The elements which follow the lanthanoids in the third transition series are known as post lanthanoids. As a result of lanthanoid contraction, the atomic radii (size) of the elements which follow lanthanum are similar to that of the elements of the previous period.

Hence, option D is correct.
