Which is a sign of dehydration?

Explanation:
Dizziness is a common and direct sign of dehydration because losing fluids reduces blood volume and cerebral perfusion, making you feel lightheaded or faint. The other options don’t fit as clearly: weight loss can occur with dehydration but isn’t an immediate, specific sign and can result from many other factors; a rash isn’t typical of fluid loss, and chills usually point to fever or cold exposure rather than dehydration.
