Answer:
A. Azure, one of our Siamese cats, was named for her piercingly blue eyes.
Explanation:
An appositive is a noun or pronoun that renames another noun or pronoun. An appositive phrase consists of an appositive and its modifiers.
In A, the appositive phrase 'one of our Siamese cats' renames the subject of the sentence 'Azure'.
This is a nonrestrictive appositive phrase. It is set off with commas because the information it provides is not necessary for identifying the noun it describes (Azure).
