Answer 1

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 are known for their malleability and lustrous appearance, and they are generally good conductors of electricity and thermal energy, although some can be brittle as well.
