Answer:
B) Whites
Step-by-step explanation:
The question is using the wrong words, being Hispanic is not a race, it is a culture. For example, almost 40% of Texans are Hispanic, while more than 80% of Texas's total population is white. There are only four races in the world: White/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid. The proper term should be non-Hispanic whites.
White/Caucasians (including or not Hispanics) are the majority of the labor force in the US, at least for a couple of decades.
