Final answer:

At birth, major connections in an infant's brain are established, but the brain is not yet in a finished state as fine-tuning and development continue postnatally. Option 1.

Step-by-step explanation:

Regarding an infant's brain at birth, it is true that (1)major connections between areas of the brain have already been formed, and the fine-tuning of the complex network in the brain has yet to occur. This emphasizes the plasticity of the infant brain and its capacity for significant growth and development after birth. The brain is not in a finished state; rather, during early childhood and into adolescence, critical processes such as synaptic pruning, increased myelination, and the formation of folds in the cerebral cortex contribute to the brain's increasing complexity and functional efficiency.
