A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Brain development does not stop after early childhood, but it is the foundation upon which the brain continues developing.

Detailed explanation-2: -Your brain has peaked by age 13. The creation of new brain cells in the hippocampus ends before we even reach adulthood, according to a study published Wednesday in the journal Nature. Previously, scientists generally believed that the human hippocampus generates new brain cells or neurons throughout adulthood.

Detailed explanation-3: -At birth, the average baby’s brain is about a quarter of the size of the average adult brain. Incredibly, it doubles in size in the first year. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5.

Detailed explanation-4: -Most of the neurons in your brain were created before you were born. But some areas of the brain make new neurons after birth in a process called postnatal neurogenesis. A few areas, including the cerebellum and the prefrontal cortex, continue adding new neurons in infancy.
