The correct answer would be option A, there are nearing retirement.

Explanation:

When a person starts his career, he usually starts from the basic level which is normally a lower managerial job. With the passage of time, with the hard work and dedication, he manages to progress in the company and goes from one management level to the other in years. So when he reaches the middle management, he is normally near his retirement age(roughly 10 to 15 years of job years left) and wants to create a backup plan for his earnings after his retirement. So the people in the middle management are most likely to invest because of their near retirement age.
