Option 1: The statement that a warm-blooded animal has a fluctuating body temperature is incorrect. In fact, warm-blooded animals are able to maintain a relatively constant body temperature, regardless of the temperature of their environment. This ability, known as thermoregulation, allows them to function optimally in a wide range of environmental conditions.

Option 2: The statement that a warm-blooded animal does not lose heat to the surroundings is not entirely accurate. While warm-blooded animals have mechanisms to regulate their body temperature, they do lose heat to the surroundings, just like any other organism. However, they are able to generate their own heat internally to counteract any heat loss and maintain a stable body temperature.

Option 3: The statement that a warm-blooded animal absorbs heat from the surroundings is also incorrect. Warm-blooded animals do not solely rely on external heat sources for maintaining their body temperature. They are capable of generating their own heat through metabolic processes within their bodies.

Option 4: The correct answer is option 4. A warm-blooded animal has a constant body temperature. This means that the animal can maintain a relatively stable internal temperature, even when the external temperature fluctuates. Warm-blooded animals achieve this by regulating their metabolic processes, such
