During the study of various principles of child development, upon a deep analysis of the 'Principle of Uniform Pattern' and the 'Principle of Integration', which of the following statements is most authentic and scientifically true regarding the philosophical, biological, and psychological interrelations of these two principles?

Understanding Child Development Principles

Among the principles of child development, the Principle of Uniform Pattern establishes that the sequence of development in all children of the human species progresses in a definite, predictable direction (such as cephalocaudal or proximodistal trends).

Simultaneously, the Principle of Integration clarifies that a child first learns minor parts or specific responses of their body organs (such as moving fingers or hands separately) and subsequently learns to combine and integrate all those motor and mental actions together into a unified whole.

• Uniform Pattern: Ensures species-specific directional consistency.
• Integration: Focuss on combining parts to function collectively.
