The correct answer is one trillion of brain connections will be present on average.
Step-by-step explanation:
When a child is recently born and has grown a little, the brain is not fully developed. For them, the brain is the part that is the least developed from all the human body. In comparison to an adult brain, a child's brain is about one-fourth the size of the adult brain. At the age of 3, the brain has made trillions of connections among the brain cells.
