Too high level of stress leads to

The correct answer is (B) Low performance.

• According to the Yerkes-Dodson Law of arousal and performance, stress acts as a psychological arousal. The relationship between stress and performance follows an inverted U-shaped curve, where optimal (moderate) stress leads to peak performance, while both very low and excessively high stress lead to diminished output.
• When stress levels exceed the optimal threshold, cognitive overload, anxiety, and mental fatigue set in, drastically reducing an individual's focus, problem-solving capacity, and efficiency.
• Option (A) is incorrect because high performance is achieved at moderate stress, not excessively high stress. Option (C) is incorrect as severe stress has distressing rather than pleasant effects. Therefore, Option (B) is the only logical deduction.
