Which organization later became the WTSDA?

• A. United States Tang Soo Do Federation
• B. Moo Duk Kwan
• C. Korean Tae Kwon Do Association
• D. Korean Soo Bahk Do Association

Answer: (A)

The question is about the historical trajectory of Tang Soo Do organizations. The World Tang Soo Do Association grew out of a United States-based group that organized Tang Soo Do in America, known as the United States Tang Soo Do Federation. As the organization expanded beyond the United States, it adopted a global focus and rebranded as the World Tang Soo Do Association. So this American federation became the WTSDA as it widened its scope.

The other options refer to different lines: Moo Duk Kwan is the original Korean school that helped shape Tang Soo Do, not the U.S. federation that became the WTSDA; the Korean Tae Kwon Do Association is Korea’s national taekwondo body, not the Tang Soo Do organization that turned into the WTSDA; and the Korean Soo Bahk Do Association is another Korean lineage, not the precursor to the World Tang Soo Do Association.
