Which principle is true about growth and development?

  • A.It occurs randomly.
  • B.It is unidirectional.
  • C.It follows a cephalocaudal pattern.
  • D.It is not influenced by genetics.

Answer: C

The true principle is It follows a cephalocaudal pattern.

Growth and development proceed from head to tail (cephalocaudal): a baby controls its head before its trunk, and its trunk before its legs. Development also proceeds from the centre outwards (proximodistal) and from general to specific.

Development is orderly and predictable, not random, and it is shaped by both heredity and environment, so 'not influenced by genetics' is wrong. 'Unidirectional' is not one of the stated principles; the accepted principle naming a direction is the cephalocaudal one.
