The correct statement that describes the properties of lanthanoids and actinoids is:

They are malleable and lustrous, and they tend to conduct both electricity and thermal energy.

Lanthanoids and actinoids typically exhibit these characteristics, particularly when compared to other elements. They are often metals, which are generally malleable and conductive.
