Refer to the given figure showing three types of thermodynamic systems (a), (b), and (c). Which of the following statements correctly identifies the boundaries and exchanges?

1. A
   System (a) is an open system exchanging both matter and energy; System (b) is a closed system with conducting walls allowing only energy exchange; System (c) is an isolated system allowing neither matter nor energy exchange.
2. B
   System (a) permits transfer of matter and energy; System (b) has a thermally insulating boundary preventing all energy transfer; System (c) permits energy exchange but prevents matter exchange.
3. C
   System (b) is an isolated system with a rigid adiabatic wall, whereas System (c) is a closed system with diathermic walls.
4. D
   Both System (b) and System (c) allow matter exchange, but System (a) restricts it via a permeable membrane.
