B
Correct answer
Explanation
Polar bears have a thick layer of fat (up to 10cm) under their skin that provides insulation against freezing Arctic temperatures. This fat layer also serves as an energy reserve during periods when food is scarce. African elephants, monkeys, and sloths do not rely on thick subcutaneous fat for thermal regulation.
