Which option defines balance?

• A. Ability to stay upright or stay in control of body movement.
• B. Stand on one leg.
• C. Ability to move quickly.
• D. Ability to coordinate two limbs.

Answer: (B)

Balance is the ability to stay upright and control body movement. Standing on one leg is the clearest, practical demonstration of that ability because it requires maintaining the body's center of gravity over a small base of support and making tiny postural adjustments to avoid falling. The other options describe related skills—speed, limb coordination, or a broad, general statement about staying upright—but they don’t illustrate balance as directly as maintaining stability on one leg.
