Answer:
B is the correct option; An email.
Explanation:
An email is the most time and resource-saving means of communicating with plenty people at a time.
A videoconference (too many people talking over one another), phone conversation (with each persona!?), conference call (where too many people will be talking over one another!?), or a webinar (seminal conducted over the internet) all seem to have each of their own faults.
But a simple email, directed to them all or even just to each person, if the info to be dished out is different per person, leaves room for each person to get a message and be able to personally reply and communicate with Polly personally and more effectively.
Hope this Helps!!!
