B: Host B will receive the frame, since Hosts B and D are in the same routing domain.
C: Host B will not receive the frame, since Hosts B and D are in the same collision domain.
D: Host B will not receive the frame, since Hosts B and D are in different broadcast domains.
E: Host B will receive the frame, since Hosts B and D are in the same bridging domain.
Answer: C
