Which factor has less control by the individual impacting performance?

The correct answer is Environmental factors. These are external conditions that can significantly influence an individual's performance but are largely beyond personal control. For example, an individual may find themselves in a high-temperature environment, at a high altitude, or in a setting with poor air quality. All these factors can affect physiological responses and overall performance but cannot be altered by personal choice or intervention.

In contrast, physiological factors are generally related to an individual's health and body, which can be influenced through training, nutrition, and lifestyle choices. Cognitive factors involve mental processes like perception, thinking, and decision-making, which individuals can develop and enhance through practice and experience. Behavioral factors pertain to actions and habits that an individual can consciously modify to improve performance.
