According to the Model Proposed in the Final Chapter of the Text

According to the model proposed in the final chapter of the text, what is the relationship between the occurrence of stable life structures and age?

A) There is an approximate link; adults who follow a modal sequence of family and work roles will share the rough timing of stable periods.
B) The linkage is very strong; virtually all adults experience periods of disequilibrium at the same ages.
C) The linkage is generally weak, but is stronger for those in the working class than those in the middle class.
D) There is no relationship at all between age and the occurrence of stable structures and disequilibrium.
