Detailed Solution

Concept: The typical baby's brain is around one-fourth the size of an average adult brain at birth. Surprisingly, it grows by a factor of two in the first year. It continues to grow, reaching around 80% of adult size by age 3 and 90%, or about full-grown, by age 5.
More than at any other period in life, at least one million new brain connections (synapses) are formed every second. From a newborn baby to an adult, the human brain grows from 100gm to 1kg in mass.
A child's brain grows the most from birth to age 5 compared to any other period of time. Additionally, a child's capacity to learn and achieve in school and in life is significantly influenced by early brain development. When a child's early talents are of good or bad quality, it can be determined how their brain will develop.
Hence, option 1 is the correct answer.
