My answer is B
Specific heart capacity , the unit is J per kg
A. same SHC because SHC is per kg
B. different SHC, because solid and liquid have different SHC, just like ice and water
C. same SHC, because SHC is independent of the shape
D. same SHC, the oil itself have same SHC, independent of the container, although the heat absorbed by the containers are different.
