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

They are brittle and dull, and they tend to conduct both electricity and thermal energy.

Lanthanoids and actinoids are typically characterized by their brittleness and dull appearance, and although they are not the best conductors compared to transition metals, they can still conduct electricity and thermal energy to some extent.
