Answer:
selective intervention.
Step-by-step explanation:
The concept of 'selective intervention' was developed by Oliver Williamson. The concept of selective intervention meant the intervention of large firms in small firms by duplicating their activities to produce net gains.
In the given case, Susan is using a selective intervention strategy as her program is assisting at-risk teens to build communicative skills, attaining academic skills, and exploring career possibilities. In this case, the firm of Susan has replicated the activities of small firms by giving at-risk teens the classes to help themselves to gain net profit.
Thus the correct answer is a selective intervention.
