Answer:
c) Move up and outward
Explanation:
When you breathe in, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, allowing your lungs to expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
