Development normally stops at about age: a 25 b 40 c 5 d development never stops

The correct answer to the question: Development normally stops at about age:, would be, around the age of A: 25.

Explanation:

For a very long time, it was believed that a person reached full maturity, especially brain maturity, at the age of 18, but after long years of research it has been found that in reality, a human person really reaches full body and brain maturity around the age of 25.
