A)it is possible to extract the 100 J of heat and convert it to work.
B)it is possible to transfer the 100 J of heat to the environment.
C)some of the heat capacity can be converted to work.
D)some of the heat capacity can be transferred to another system if there is a temperature difference.
E)(C)and (D)

Heat capacity is a measure of the amount of heat energy required to change the temperature of a system. It does not imply that all of this energy can be converted to work (due to the second law of thermodynamics), but it does mean that heat can be transferred to or from the system, including potentially doing some work or transferring heat to another system if there is a temperature difference.
