The insertion of the scalene muscles is which of the following?

Explanation:
Scalene muscles attach to the first two ribs, which is where they act to lift the rib cage during deep breathing and assist neck movements. Specifically, the anterior and middle scalene attach to the first rib, and the posterior scalene to the second rib. That makes the insertion on the first and second ribs the best description. The transverse processes of the cervical vertebrae are where these muscles originate, not insert, so that option describes their origin. The other options describe noninsertion landmarks and don’t match the actual attachments.
