Sternocleidomastoid is supplied by all of the following aeries except?

C i.e. Thyrocervical trunkSternocleidomastoid muscle receives its blood supply from branches of occipital & posterior auricular aeriesQ (upper pa of muscle), the superior thyroid aery or branches of external carotid aery (middle pa of muscle) and the suprascapular aery (lower pa of muscle) Although suprascapular aery is a branch of thyrocervical trunk, it seems to be the most appropriate answer as all other options directly supply the muscle.
