Answer:
The correct answer is - holder-on type.
Step-by-step explanation:
The behavior of Ken towards his retirement and age shows that he is an individual that is ambitious, striving but having high defenses against anxiety and wanted to have control of all the events, even the events that can not be controlled.
This shows that he is an individual of holder-on type as he finds age as a threat and trying to avoid or fight with it.
Thus, the correct answer is - holder-on type.
