Which one of the following is a factor affecting the physical development of a child?
Detailed Explanation & Solution
📌 Core Theoretical Concept:
Physical development in children is a continuous process governed by both biological and environmental influences. However, heredity is universally recognized as the primary internal determinant of physical traits such as height, weight, body structure, bone density, and overall physiological makeup. Option 'a' (Heredity) is the correct answer because genetic factors set the biological baseline and potential for an individual's physical growth and maturation, whereas teachers, companions, and religious places primarily influence social, emotional, and moral domains rather than direct physical growth.
📊 Key Exam Points:
- Heredity dictates the foundational blueprint for physical attributes, body type, and biological capacities.
- Teachers, peers, and religious settings contribute significantly to social, cognitive, and affective domains rather than biological physical changes.
- Development is the dynamic product of interaction between heredity and environment (Development = Heredity × Environment).
- Physical development encompasses gross and fine motor skills, skeletal growth, and organ maturation.
📖 Theoretical Reference: According to developmental psychology, maturation is heavily dependent on genetic scheduling, while environmental factors can enhance or restrict this natural trajectory. Explore more about Principles of Child Development and maturational processes.

Deep Pedagogical Analysis:
In competitive teacher eligibility tests like CTET, DSSSB, and SuperTET, questions distinguishing between nature and nurture are common. Physical development is largely a function of biological maturation (Nature/Heredity), while social agents like peers and teachers fall under environmental influences (Nurture). Aspirants must carefully analyze whether a given factor impacts the biological domain or the psychosocial domain to accurately answer questions regarding child development domains.
