Dehydration can be described as a ________ water loss within the body, resulting in a drop in performance.

B.) 5%

The correct answer is D.) 3%

To find the answer to this question, we need to understand what dehydration is and how it affects the body. Dehydration occurs when there is an inadequate amount of water in the body. It can be caused by various factors such as excessive sweating, insufficient fluid intake, or certain medical conditions.

The question states that dehydration can be described as a specific percentage of water loss within the body resulting in a drop in performance. We need to determine which percentage is the correct answer.

According to medical professionals, as little as 1% to 2% loss of body weight as water can lead to mild dehydration. This level of dehydration can already impact cognitive function, decrease physical performance, and impair endurance. As the water loss percentage increases, the severity of dehydration and its effects become more pronounced.

Looking at the answer choices, we can conclude that the correct answer is:
A.) 2%
