What does the PGA stand for?

The correct meaning of the acronym PGA is "Professional Golf Association of America." The term "Professional Golf Association" is a general descriptor and does not provide the specific context necessary to identify the well-known organization. The PGA is a significant governing body in the golf industry and represents professional golf in the United States, involved in various aspects of the game including education, tournaments, and promoting the sport.

The PGA exists primarily to support and further the careers of golf professionals, and its full name reflects its specific location and authority within the country. Unlike the other options, which either refer to a less accurate aspect of the organization or do not fully encompass its identity and purpose, selecting the complete name gives a clear understanding of the organization's role in professional golf.
