Which league was the groundbreaking women's baseball league during World War II that demonstrated women's ability to compete in professional baseball?

• A. All-American Girls Professional Baseball League (AAGPBL)
• B. Women's Baseball League
• C. National Women's Baseball League
• D. Ladies' Baseball Association

Answer: (A)

When men went off to fight in World War II, baseball still needed to be played at a high level, and this opened opportunities for women to compete professionally. The best and most influential example of that era is the All-American Girls Professional Baseball League, established in 1943. It was a true professional league with organized teams, seasons, and salaries, and it demonstrated that women could play baseball at a high level and hold their own against male players.

This league not only kept the sport visible during the war but also challenged widespread assumptions about women's athletic abilities and helped pave the way for future generations of female athletes. The other names listed aren’t associated with a real, widely recognized WWII-era professional women’s league, so they don’t match the well-documented history of women breaking into professional baseball at that time.
