The transformative capacity of taking a certification course to improve your role and pay is best defined as A. power.
What is power in this context ?
Power is the ability to influence others or to control situations. In this case, the young professional is gaining power by acquiring new skills and knowledge that will make them more valuable to their employer.
This newfound power will allow them to negotiate for a better position and salary.
Hegemony is the dominance of one group over another. In this case, the young professional is not dominating their employer; they are simply improving their position within the corporate hierarchy.
