Which statement shows insight into the client's use of the defense mechanism of displacement?

The statement that reflects insight into the client's use of the defense mechanism of displacement is the one highlighting how the individual talks to their wife instead of their kids when feeling upset. Displacement is a defense mechanism where feelings or impulses are redirected from the original source of frustration to a more acceptable object or person, often because it feels safer or less threatening to express emotions elsewhere.

In this case, the client recognizes that when they are upset, they are not expressing their feelings directly to the source of their upset—presumably, their children. Instead, they choose to talk to their wife, indicating an understanding of how they manage their emotional responses. This awareness of shifting emotions from one target to another showcases insight into their psychological processes.

The other statements do not demonstrate the same level of understanding regarding displacement. They focus on ignoring feelings, distracting oneself, or achieving academically without the direct acknowledgment of redirecting feelings towards a safer target. These reflections point more towards avoidance or other defense mechanisms rather than the specific act of displacement, where there is a clear identification of shifting emotions from one source to another.
