While analyzing the 'Principles of Development' during the study of child development, which of the following pairs most accurately demonstrates the direction and pattern of development?

Child development is a gradual and systematic process that follows certain universal principles.

• Cephalocaudal sequence: Physical development proceeds in the direction from head to toe (an infant first learns to control the head, then the torso, and finally the legs).
• Proximodistal trend: Development starts from the center of the body (spine or trunk) and proceeds outward toward the periphery (hands and fingers).

Development is never strictly linear; rather, it follows a spiral path and is the result of the interaction between heredity and environment.
