The correct option is NON RESTRICTIVE PHRASE. A non restrictive phrase usually describes a noun in a non-essential manner. A non restrictive phrase provides additional but optional description which can be removed from the sentence without altering the overall meaning of the sentences. For instance, in the sentence given above, the phrase ' the basketball player' can be removed from the sentence without changing the meaning of the sentence. The remaining portion of the sentence will reads ; Micheal Jordan won six championships for the Chicago Bulls.
