Answer:
D-unconditional positive regard
Step-by-step explanation:
Carl Rogers would most likely describe Brett's belief as an example of unconditional positive regard. This is basically when you believe that an individual should be accepted and supported regardless of the person's actions, ideas, or behaviors. In this scenario, this is in regards to children in general, and since Brett believes that they should be treated with love and support at all times regardless of their behavior, it matches with the idea of unconditional positive regard. Therefore, it is a clear example of this as Carl Rogers would describe it.
