Answer:
Informational Influence.
Step-by-step explanation:
The theory of Informational Influence was developed by Harold B. Gerard and Morton Deutsch. Informational Influence can be defined as a piece of new information that is gained during a group discussion. This information provided in the group discussion tends to change the beliefs, behavior or the viewpoint of an individual or some member's of the group.
In the given scenario, Dominic's dependence on his group is an example of Informational Influence. Dominic is unaware of an answer and he is relying on his group to provide the information. This information that will be shared will also help Dominic to have a correct answer to the question.
So, the correct answer is Informational Influence.
