Which group was granted the right to vote by the 19th amendment to the constitution?

The 19th Amendment to the U.S. Constitution, ratified in 1920, specifically granted women the right to vote in federal and state elections. This landmark amendment was the culmination of a long struggle for women's suffrage, which aimed to secure equal voting rights for women across the United States. The impact of the 19th Amendment was profound, as it marked a significant turning point in the fight for gender equality and helped pave the way for future civil rights advancements.

In contrast, the other groups mentioned in the answer choices pertain to different aspects of voting rights. Males already had the right to vote prior to the 19th Amendment, as that right was largely reserved for white males in the early years of the United States. The option referring to all citizens includes groups who may not have been enfranchised at that time, such as women before the amendment and racial minorities, since their voting rights were still being fought for in subsequent years. The mention of people of all races also reflects a key issue in American history, as voting rights for people of color faced additional barriers that extended beyond gender. Hence, the 19th Amendment is specifically and historically significant for granting voting rights to women.
