Which of the following plays an important role in developing an individual's physical characteristics?

Correct option is C

Ans. (c)
Sol. Heredity plays a crucial role in developing an individual's physical characteristics. It determines traits such as height, skin color, eye color, and facial features, which are passed down from parents to offspring through genetic material (DNA). While environmental factors can influence development, hereditary traits are inherited and largely fixed.
Explanation of each option:
· (a) Socio-cultural factors – Incorrect, as these influence behavior, lifestyle, and personal choices rather than inherent physical traits.
· (b) Mental attitudes – Incorrect, as mental attitudes affect personality and behavior but do not directly determine physical characteristics.
· (c) Heredity – Correct answer. It determines an individual’s genetic traits, influencing physical attributes.
· (d) Personal habits – Incorrect, as habits affect health and fitness but do not fundamentally shape inherited physical characteristics.
