Answer: B. Ethnicity, with preference given to Hispanic candidates.
Step-by-step explanation:
During the selection of employees for a particular job role, it is legal to assess them using certain tests. These tests must, however, be job-related and must not discriminate against protected groups. Protected groups include race, gender, age, disability, religion, skin color, etc.
In the case of 'XPatriot', all the criteria mentioned before the selection of employees who are to move to South America are all job-related except choosing on the basis of Ethnicity. This is because an employee may not be Hispanic but could meet the other more important criteria. Not choosing him would amount to some level of discrimination.
