The wood block has a density greater than 1.0 g/cm3 and the gold block has a density lower than 1.0 g/cm3

B.
The wood block has a density lower than 1.0 g/cm3 and the gold block has a density greater than 1.0 g/cm3

C.
Both blocks have a density lower than 1.0 g/cm3

D.
Both blocks have a density greater than 1.0 g/cm3
