I'm not understanding why D is the correct answer choice for this question, help is appreciated!

My thinking:

Given that the author states that the Maya have to rely on other countries' precedents because "courts in Belize have not yet ruled on... indigenous rights" and that there is an "absence of relevant precedent in Belize's case law" I don't know how the author's purpose can then be to suggest that "the courts of Belize have relied upon the sorts of common law precedents that the Maya argue should be applied."

In my head, it is inconsistent to suggest that there is both an absence of "relevant" precedent in Belize law (meaning nothing even close can be applied) and to suggest that Belize courts have "relied... upon the sorts of... precedent the Maya argue should be applied."

Where am I messing up? Thanks!
