In the study of child development, analyzing the concepts of 'Growth' and 'Development' along with various principles of development (such as the proximodistal trend and cephalocaudal trend), which of the following statements most accurately defines the scientific and psychological nature of these principles?

In child psychology, 'Growth' primarily refers to quantitative changes in physical size, weight, and structure which stop after a certain time, whereas 'Development' is a lifelong, comprehensive, qualitative, and organized process. Development follows certain principles; for example, according to the 'cephalocaudal trend', development occurs from head to toe, and according to the 'proximodistal trend', development proceeds from the central part of the body (trunk or spinal cord) toward the peripheral organs (hands and feet).
