Final answer:
Projection and Denial are examples of immature defense mechanisms; they allow individuals to avoid acknowledging distressing thoughts and realities.
Step-by-step explanation:
The immature defense mechanisms are unconscious strategies used by individuals to protect themselves from anxiety and the perceived threats of reality. Among the options provided, Projection (A) and Denial (B) are both considered immature defense mechanisms. In comparison, Altruism (C) and Humor (D) are typically seen as more mature defense mechanisms that allow individuals to handle stress in a more adaptive way.
Projection involves attributing one's unacceptable thoughts, feelings, or motives to another person. This can relieve anxiety by allowing the individual to express the impulse without having to acknowledge it as their own. Denial, on the other hand, involves refusing to accept the reality of a distressing situation, reducing anxiety by simply ignoring the problematic aspects of one's environment or experiences.
