According to Samuel Gompers and the AFL, the right to unionize, strike, and boycott stemmed from:

A) Individual liberty and freedom.
B) Property rights.
C) Rights granted to incorporated organizations.
D) Legal precedent.

Samuel Gompers and the AFL believed that the right to unionize, strike, and boycott stemmed from the principles of individual liberty and freedom. They argued that workers should have the right to come together and form unions to advocate for better working conditions and fair wages. Gompers also believed that the ability to strike and boycott was essential for unions to be effective in achieving these goals. This view is consistent with the broader tradition of labor rights activism, which has emphasized the importance of workers' rights to self-organization and collective action.
