B. Immigrants took jobs from Americans.
Step-by-step explanation:
The arguments about immigration is typically not about legal immigrants, but rather, about illegal immigrants. Illegal immigrants are forced not to comply with the law, as, if they are found out, will be deported, forcing them to have to accept jobs that are paid less. However, workplaces who do not need a certain skill set may actively seek out illegal immigrants, as they can be paid for less then the minimum wage, as well as allowing work conditions to be more lenient (which typically means under the federal safe levels).
