When micro-analyzing the 'Principle of Interrelation' and the 'Principle of Individual Differences' among various principles of child development, if a child's physical development occurs at a rapid pace, but their mental or social development does not progress at the same rate, which of the following statements is most authentic regarding the fundamental nature of child development?

Detailed Explanation

In the process of child development, the 'Principle of Interrelation' clarifies that a child's physical, mental, emotional, and social developments are deeply interconnected. For instance, if a child is physically weak due to malnutrition, their cognitive and mental development may also be hindered.

At the same time, the 'Principle of Individual Differences' states that the rate of development can vary from person to person, but the interconnected domains mean progress in one area influences others. Therefore, option (b) presents the most accurate and scientific analysis of this concept.
