What does the term 'stymie' mean?

The term 'stymie' means to hinder or prevent progress, which directly aligns with the definition provided in the correct answer. Originating from the game of golf, where to 'stymie' an opponent means to obstruct their path to the hole, the term has broadened to encompass any situation where an obstacle or challenge blocks someone from achieving a goal or making progress. This can apply to a variety of contexts, such as personal endeavors, professional projects, or broader societal issues.

In contrast, the other options suggest positive actions—facilitating, encouraging, or providing support—all of which imply helping someone move forward or make progress. These definitions are oppositional to 'stymie,' which clearly conveys the idea of obstruction or hindrance. Thus, recognizing the nuances of 'stymie' in terms of impeding progress clarifies why the answer selected is indeed correct.
