Answer 2

Answer:

The answer that contains correct punctuation is B. In some areas—the deserts of Arizona and Mexico, for example—cacti are native.

Explanation:

Sentence B is the correct answer because it uses dashes. Dashes are punctuation marks that introduce an interruption or abrupt change of thought in writing, or that add emphasis within a sentence.  Usually, there are no spaces around dashes.
