Settings for article submission?

If i want to submit only articles for Type of Backlinks to Create i have to select only these: Article, Article Wiki, Anchore Text. Correct?

Yes.

But I think if you just want contextual platforms, it would only include "Article" and "Article Wikis" and not anchor text type. At least that is what I have heard from people over here. Others maybe able to guide you more thoroughly.

Yes, just use Article and Article-Wiki.
