The Anterior Scalene muscle is used to divide the subclavian artery into three parts. Here's how:

1. The first part of the subclavian artery extends from its origin to the medial border of the anterior scalene muscle.
2. The second part of the subclavian artery lies posterior to the anterior scalene muscle.
3. The third part of the subclavian artery extends from the lateral border of the anterior scalene muscle to the outer border of the first rib, where it becomes the axillary artery.

So, the correct answer is Anterior Scalene.
