C. Sore muscles

Explanation:

Poor posture occurs when the body becomes accustomed to an erratic position of comfort, such as sitting crookedly in a chair. This is a big problem in modern society, since many people work and study sitting and others need to use the physical effort to work, like construction workers. Poor posture can cause muscle and bone pain and should be prevented through awareness. If necessary, a person should consult a doctor and have physical therapy to fix the posture.
