6- Consider five wireless stations, A, B, C, D, and E. Station A can communicate with B, and C. B can communicate with all other stations. C can communicate with A, and D. D can communicate with A, B, and E. E can communicate with B, and A. When station B is sending to D, what other communications are possible? (Assume that stations are using MACA protocol)
