• B. It prevents fatigue and puts less stress on the muscles
• C. It improves digestion
• D. It increases appetite

Answer: (B)

Posture affects how your muscles and joints share the work of supporting the body. When your spine is in a neutral, aligned position, muscles work together efficiently to hold you upright, so you don’t have to recruit extra effort from them. Slouching or hunching forces certain muscles to compensate, which means more energy is spent just keeping you up and carrying out daily movements. Over time this extra effort leads to fatigue and a higher risk of muscle strain or discomfort. Good posture distributes the load more evenly across the back, neck, and shoulders, reducing unnecessary stress and helping you feel steadier and less tired after activity. While upright posture can also aid breathing, the primary reason it’s necessary is that it minimizes fatigue and muscle stress by promoting efficient, balanced movement.
