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 typically metals, and while they can be somewhat malleable and lustrous, they are generally considered good conductors of electricity and thermal energy. However, it's worth noting that actinoids can exhibit more complex behaviors due to their radioactivity and the influence of f-electrons.
