- Thyrocervical trunk (b) seems to be the most appropriate answer, because it is not directly supplying the muscle, though suprascapular artery is a branch of thyrocervical trunk and supplies the lower part of sternocleidomastoid.
- Upper part of the muscle is supplied by the occipital (c) and posterior auricular (d) artery.
- Middle part is supplied by the superior thyroid (a) artery.
