In the context of various principles of child development, which of the following is the most accurate analysis of the fundamental and physiological-psychological process between the 'Cephalocaudal Sequence' and the 'Proximodistal Sequence' falling under the 'Principle of Directional Sequence'?

Understanding the Principle of Directional Sequence

The 'Principle of Directional Sequence' is crucial in the process of child development. It encompasses two primary trends:

• Cephalocaudal Sequence: According to this, physical and motor development proceeds from the head downward toward the feet (i.e., the infant gains control of the head first and the legs last).
• Proximodistal Sequence: According to this, development starts from the central axis of the body and moves outward toward the peripheral limbs, i.e., from the spinal cord outward to the hands and fingers.

Therefore, option B provides the most accurate scientific analysis of both developmental directions.
