C. It can allow for deep breathing and proper digestion.

Have you ever tried taking a deep breath while sitting uncomfortably? It's not exactly easy, and doesn't feel to good, haha. 

Hope this helps :)
I believe it's B and C, because good posture can aide in proper alignment of organs such as stomach, intestines, bladder and so on. Good posture is also good your back and all of Your Vertebrae as well as the spinal column. So utilizing good posture throughout ones younger years, can add more years of active, and pain free years of life.
