Which of the following is a duty of a PGA professional?

Maintaining the integrity of the game is fundamental to the role of a PGA professional. This duty encompasses upholding the traditions, values, and standards of golf, ensuring fair play, and fostering a positive environment for all participants. PGA professionals are often looked up to as leaders in their communities and are expected to model good sportsmanship and ethical behavior, which contributes to the overall reputation and integrity of the sport.

In contrast, pursuing personal gain, focusing solely on tournament success, and merely promoting equipment sales do not align with the broad responsibilities that come with being a PGA professional. These roles would limit the professional's focus and could lead to conflicts of interest or undermine the spirit of the game. The primary objective of a PGA professional is to elevate the sport, educate players, and enhance their experience rather than prioritize personal success or commercial interests above all else.
