In the context of various principles of child development, which of the following is the most accurate and scientific distinction between the 'Cephalocaudal' and 'Proximodistal' laws of development falling under the 'Principle of Directional Trend'?

The 'Principle of Directional Trend' in child development clarifies that physical and motor development progresses in a definite and predictable direction. It has two main dimensions: 1. Cephalocaudal: According to this, development starts from the head and moves downward toward the feet (which is why an infant first learns to control their head and later learns to stand or walk). 2. Proximodistal: According to this, development starts from the center of the body and moves toward the periphery (outward toward the hands and fingers, meaning organs near the spinal cord develop first and finger control comes later).
