Which statement correctly defines the Centre of Gravity in humans?

• A. The Centre of Gravity is the average location of body weight (hips).
• B. It is the average center of upward lift in water.
• C. It is the point where water pressure is greatest.
• D. It is the point of maximal muscle density.

Answer: (A)

Centre of Gravity is the point where the body's weight can be considered to act; it’s the balance point, the weighted average of all body masses. In humans, because different body parts have different densities and masses, the CG sits in the lower torso region, around the hips/pelvis, and shifts with posture. This is why describing it as the average location of body weight around the hips is the best way to define it. The other ideas refer to buoyancy in water, water pressure, or tissue density, which are not what determines the Centre of Gravity.
