To understand the communication traffic between these members, the organization created the following graph.





What are the closed communication groups of the gang members?


A) {Michael, Sophie, Daniel, Olivie, Lucas, Emma, ​​Ryan}, {Chloe, Ethan}

C) {Chloe}, {Ethan}, {Michael, Sophie, Daniel, Olivie, Lucas}, {Emma, ​​Ryan}


D) {Michael, Sophie, Daniel, Olivie}, {Lucas, Emma, ​​Ryan}, {Chloe}, {Ethan}


E) None of the above
