Rogers believed that a fully functioning person:

A) represses negative feelings.
B) develops defenses against threats to the self.
C) relies on stereotypes to judge people.
D) is open to all experiences and feelings.

Rogers believed that a fully functioning person is someone who is open to all experiences and feelings, is aware of their own emotions and accepts them without judgment or self-criticism. They also have a sense of unconditional positive regard towards themselves and others, which means they do not rely on stereotypes to judge people. Additionally, Rogers did not believe in the use of defenses as a means of dealing with threats to the self. Thus, option A and B are incorrect.
