Answer:
b. impulses; protect our self-image.
Step-by-step explanation:
Freud believed that defense mechanisms resulted from impulses, but researchers now believe that they result from a need to protect our self-image. According to Sigmund Freud, we use defense mechanisms to protect ourselves from unpleasant impulses and feelings, such as anxiety or guilt. These mechanisms are unconsciously applied to protect a person from what is seen as threatening or unpleasant. Researchers now have stated that these defense mechanisms serve to protect our self-image.
