When an object of volume V0 and density ρ0 is immersed in a fluid of density ρf, its weight is reduced due to the buoyant force. Which of the following is a correct mathematical expression of the apparent weight of an object (Note: g = acceleration due to gravity)?
A. ρ0V0g
B. ρfV0g
C. (ρf - ρ0)V0g
D. (ρ0 - ρf)V0g
