• B. Eugene V. Debs
• C. Henry Clay Frick
• D. Terence Powderly

Answer: (D)

The Knights of Labor experienced significant growth in the 1880s under the leadership of Terence Powderly. Powderly, who became the organization's Grand Master Workman in 1879, was instrumental in expanding the membership and influence of the Knights. His leadership emphasized inclusivity, welcoming not just skilled white males but also women, African Americans, and unskilled laborers into the fold. This approach marked a departure from many labor organizations of the time that were more exclusive in their membership.

Under Powderly’s guidance, the Knights of Labor advocated for broad social reforms, including the establishment of an eight-hour workday and improvements in labor conditions. The organization’s emphasis on a holistic vision of labor rights resonated with many workers during this period, contributing to the rapid increase in its membership from around 20,000 to over 700,000 by the mid-1880s. Powderly's ability to galvanize workers across various occupations and backgrounds was a pivotal factor in the Knights' expansion and helped propel the American labor movement into a more prominent national discourse.
