Answer:
B). Free will.
Step-by-step explanation:
Free will theory is illustrated as the ability to select the action from a number of impeding behaviors or actions. It implies that an individual is free to choose and determine his/her course of action or behavior or fate.
As per the question, the theory that describes Cora's belief would be 'free will' as she uses her ability to choose her course/manner of action('she decides she wants to be a better listener') which she herself feels guilty about her 'interruption in conversations' that is also known as 'self-determination'. However, an individual is not completely free to choose or determine as sometimes we are governed by the social, political, and emotional activities that may influence this. Thus, option B is the correct answer.
