Leadership roles first emerge in which of the following kinds of communication?

Leadership roles first emerge in small group communication, where members interact closely enough for one to guide the rest.

As a handful of people coordinate a shared task, some take initiative and a leader naturally surfaces.

Silent self-talk within one mind is intrapersonal communication, which has no group and no leader can arise within it.

Face-to-face public communication has a speaker already fixed before an audience, so leadership is preset, not emerging.

Communication through cell phones and instant messenger is mediated contact, not the setting where leadership roles first form.

The small group is the earliest arena in which shared goals and interaction let leadership develop.
