What change occurs in perception when the Sympathetic Nervous System is activated?

When the Sympathetic Nervous System is activated, particularly during situations involving stress or danger, the body enters a heightened state of alertness. This activation leads to several physiological responses, including the adjustment of hearing and vision. The body reallocates resources to enhance sensory input that is critical for responding to threats in the environment.

For instance, pupils dilate to allow more light into the eyes and improve visual acuity, while hearing may become sharper to detect potential dangers in the surroundings. This enhanced sensory awareness is crucial for survival, as it equips an individual to respond more effectively to immediate challenges or stressors. Thus, option B accurately describes the physiological and perceptual changes that occur with the activation of the Sympathetic Nervous System.
