The paired cartilages that articulate with the superior border of the cricoid cartilage are the cartilages.

The correct answer is "arytenoid".

Explanation:

The paired cartilages that articulate with the superior border of the cricoid cartilage are the arytenoid cartilages. Arytenoid cartilages are comprised of a pair of small three-sided pyramid that are attached to the vocal cords, along with the cricoid cartilage, a ring of cartilage that surrounds the trachea.  Arytenoid cartilages are essential to the vocal cords' movement.
