Final answer:
The correct order of development stages from greatest plasticity to least is Infancy, Childhood, Adolescence.
Step-by-step explanation:
The question asks about the order of the stages of development from greatest plasticity to least plasticity. During infancy, there is the highest level of plasticity because this is a time of rapid physical and cognitive growth. Childhood follows infancy and also shows significant growth, but not as rapidly as infancy. Adolescence is a period of important mental, emotional, and social changes as well as the physical changes of puberty, but plasticity is lower compared to infancy and childhood. Therefore, the correct order of these stages from greatest to least plasticity is Infancy, Childhood, Adolescence, which corresponds to option (a).
