responsibility acquisition achievement reintegration?

Answer: A) Responsibility

Explanation: According to Schaie, there are seven stages of cognitive development and responsibility is one of them. This stage occurs during the said period of maturity and is characterised by the use of acquired knowledge to solve problems. All problems that are solved are related to the responsibility of the one who solves them, so solving problems is the result of someone's responsibility. This implies both professional and personal responsibility. In practical terms, this means, to solve and optimise the professional and personal situation, i. e to act responsibly, and above all, responsibility in this period refers to the care of the family.
