Which term means 'pertaining to the lining of an artery'?

Explanation:
Understanding how medical terms are built helps here. endo- means within, arteri- refers to arteries, and -al means pertaining to. Put together, endarterial describes something pertaining to the inner lining of an artery. The inner lining is the region the term points to, so endarterial fits perfectly for “pertaining to the lining of an artery.” The other options don’t describe this tissue or location: a term for a body region (lower limb), a bone-density condition (osteopenia), or a root related to radius/radiation (rad/i).
