The question states that all people come very close to being able to float in water. This means that the weight of the person is approximately equal to the weight of the water they can displace. The density of water is 1000 kg/m^3. Therefore, the volume of water displaced by the woman is 50 kg / 1000 kg/m^3 = 0.05 m^3. This is also the volume of the woman herself, so the answer is C.
