All parties need to communicate about strategy and schedule. which communication channel is most likely to meet their needs? multiple choice a conference call a series of one-to-one phone calls a videoconference an electronic discussion thread a face-to-face meeting

The most suitable strategy for all parties to communicate is by using a videoconference in which allows all of the people to have a meeting and to be able to see each of the people involved in a meeting. Using a conference call may also be useful but the lacking of it is that you may not be able to see the people you're talking to. Other choices aren't suitable as this will not allow you to talk to everyone all in the same time.

Ibelieve the answer is ethos which is an appeal to ethics
