According to Schaie,a person who is working and is put into a position to supervise others would be in the ______ stage.

A) acquisitive
B) achieving
C) executive
D) reorganization

The executive stage in Schaie's theory of cognitive development occurs typically in middle adulthood and is characterized by people taking on managerial roles, supervising others, and using their knowledge and experience to guide decision-making. Therefore, a person who is working and is put into a position to supervise others would be in the executive stage. The other options (acquisitive, achieving, and reorganization) do not fit the description of this scenario.
