Answer 1

The statement that the human brain at birth has a full supply of neurons is false. The answer is option A.

Step-by-step explanation:

All of the statements about brain development listed are true except for the statement that the human brain at birth has a full supply of neurons. The human brain does not have a full supply of neurons at birth; instead, the majority of neural connections and pathways occur during the first few years of a child's life. This period of rapid neural growth is followed by a period of pruning, where neural connections are reduced to allow for more efficient brain function.

Neurogenesis, the process of generating new neurons, continues in certain regions of the brain throughout life, although the rate diminishes significantly after early childhood. At birth, the brain already has a substantial number of neurons, but further development and maturation occur postnatally.
