The correct answer is C. Assigning group roles
Explanation:
In communication, a group discussion is a type of communicative situation in which different participants share their ideas and points of view to achieve the main goal such as analyzing some material or providing a solution for a problematic situation. Additionally, there are other elements or procedures that need to be followed to guarantee the discussion is effective this includes setting rules for the discussion, assigning a specific time for all the stages in a discussion and assigning group roles.
In the case of assigning group roles, this refers to assigning different the different tasks that need to be completed during the discussion, for example, one participant should be in charge in giving turns for the participants to speak, another should check the time and another should summarize the main ideas after the discussion. This usually makes all the participants be engaged in the communicative process and assume their responsibility for the whole group and the whole discussion. Thus, the step that enables everyone to assume responsibility for the entire group is "assigning group roles".
