Animals respond to hot temperatures by perspiring or panting, which helps regulate their body temperature by evaporating water from their skin and respiratory system. In addition, animals may dilate blood vessels to release heat from their body. This allows the blood to flow closer to the skin's surface, resulting in heat loss. By contrast, constricting blood vessels would conserve heat and raise body temperature. Therefore, Option A is the correct response. The other options are incorrect as they do not reflect the physiological responses of animals to hot temperatures.
