Answer:
c) Biology and experience
Explanation:
Physical development can be defined as the physical and biological advancement, as well as refinement of gross and fine motor skills that occurs in human beings between birth and adolescence. As children grow physically and psychologically, the ability to use and control their body increases. Similarly, they acquire knowledge and experience from their peers, family and environment as they grow.
This ultimately implies that, physical development involves the growth of a child and his or her ability to use muscles, bones and other body parts to perform some specific skills.
Hence, physical development is determined through biology and experience because it is typically based on factors such as weight, height, sexual development, intelligence, head size, etc.
