Step-by-step explanation:
The theory where an intrinsic form of motivation drives one's work tasks as they believe they are contributing to some larger purpose is Self-Determination Theory (c).
Self-Determination Theory is a psychological theory that states that people have three basic psychological needs - autonomy, competence, and relatedness - and when these needs are met, they are more intrinsically motivated to engage in activities and work towards goals.
