Deborah Tannen, a professor of linguistics studied whether one form of interaction dominates American culture and also suggested that Americans live in an argument culture.

Option C, both a and b.

Explanation:

Deborah Tannen, who is a professor of linguistics in Washington DC University of Georgetown, her research is mainly focused on the interpersonal relationships expressions in conversational interactions. She highlighted that in US families the mothers is the one that encourages their child to speak about they day to the father, a mother makes the children expressive toward their father, this the "telling your day" ritual.

This ritual also involves a woman sharing some frustrating experience with a confidant whom she trusts. She also says that women consider closeness with someone to whom they can share their personal details. This gender misinterpretation suggests that Americans live in an "argument culture", and one part of  interaction dominates the American culture in all way possible.
