The correct answer is adolescence.
Adolescence is the transition period between childhood and adulthood.
The terms comes from Latin adolescere which means to grow up.
This is a transition stage starting with puberty (physical changes in a child's body preparing them for sexual reproduction) and ending with the legal age of maturity ( legal adulthood, usually 18 years of age).
The changes in adolescence include physical ones: termination of physical growth, changes to the sex organs and changes in the brain structures. The social changes include development in cognitive behavior, adaptation of new roles in society and an increase in interest in the opposite sex.
