Which term denotes the front end of an annelid?

Explanation:
The front end of an annelid is described by the term anterior, which in bilateral animals refers to the head region. Annelids have a prostomium at the very front that forms part of the head over the mouth, but that’s a specific structure rather than the directional label for the front. The clitellum is a swollen region involved in reproduction located mid-body, not the front, and posterior refers to the rear end. So anterior best denotes the front end.
