Radhika wants to do everything perfectly. Everytime this expectation leads to disappointment and stress. Thus, the source of her psychological stress is _________.

Internal Pressure

The correct answer is Internal Pressure.

Radhika's psychological stress stems from her internal pressure to achieve perfection. This self-imposed expectation leads to disappointment and stress when she falls short of her unrealistic standards. This internal conflict between her expectations and her actual performance is the source of her psychological stress.

The other options are not as accurate:

• Frustration is a negative emotion that arises when someone is unable to achieve a goal or satisfy a need. While frustration can contribute to stress, it is not the primary source of Radhika's stress in this scenario.

• Conflict refers to a disagreement or clash between two or more opposing forces. While Radhika may experience conflict with others due to her high expectations, the primary source of her stress is her internal struggle with her own standards.

• Social pressure refers to the influence that people exert on others to conform to their expectations. While social pressure can also contribute to stress, it is not the primary source of Radhika's stress in this scenario.
