In the laboratory, you are given a 18.5 g sample of an unknown metal. The sample is irregular in shape, conducts heat and electricity well, and sinks in water. The sample is placed into a partially filled graduated cylinder and displaces 2.06 mL of water. The sample is then heated to 160℃ with a Bunsen burner. The hot metal is placed into a calorimeter filled with exactly 50.0 g of water. The water temperature rises from 20℃ to 24.6℃ . Using the above information and data table provided below, identify the metal and explain your reasoning.

Metal Density (g/cm3 ) Specific Heat (J/g*℃ )
A 8.96 0.385
B 8.96 0.233
C 8.65 0.231
D 7.31 0.385
Water 1.00 4.184
