Answer: (C)

Verified step by step guidance

1. Understand that brain growth in developmental psychology refers to the physical growth and maturation of the brain's structure, including the development of neurons, synapses, and myelination.
2. Recognize that while rapid brain growth occurs during infancy and early childhood, the brain continues to develop and change well into adolescence and early adulthood.
3. Identify that the process of brain maturation, including synaptic pruning and myelination, extends beyond childhood and is not complete by age 5, 12, or even 18.
4. Recall that neuroscientific research shows that brain development, particularly in the prefrontal cortex responsible for higher cognitive functions, continues until the mid-20s.
5. Conclude that the typical age by which brain growth and maturation largely stop is around age 25, reflecting the extended period of brain development.
