The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Allen's Rule**: Allen's Rule is a principle in biology that explains how the physical characteristics of animals adapt to their environments, particularly in relation to temperature. 2. **Application to Mammals in Cold Climates**: According to Allen's Rule, mammals that inhabit colder climates tend to have shorter limbs and body parts compared to their counterparts in warmer climates. 3. **Reason Behind Shorter Limbs**: The rationale for this adaptation is that shorter limbs and body parts have a smaller surface area relative to their volume. This reduced surface area minimizes heat loss, which is crucial for survival in cold environments. 4. **Examples of Mammals**: Examples of mammals that exhibit this adaptation include polar bears and arctic foxes, which have shorter ears and limbs compared to similar species found in warmer climates. 5. **Conclusion**: Therefore, according to Allen's Rule, mammals from colder climates have shorter limbs and body parts to conserve body heat. ---
