Final answer:
The question that should not be asked during an interview is (C) Do you have any children?
Step-by-step explanation:
During an interview, it is important to be aware of the questions that are considered illegal and discriminatory. One such question is "Do you have any children?" This question is prohibited by the Civil Rights Act of 1964, which aims to protect job applicants from employment discrimination based on personal characteristics such as family status. Asking about an applicant's family status, including whether they have children, can create bias and lead to discrimination in the hiring process. Therefore, it is important for interviewers to refrain from asking such questions and focus solely on the applicant's qualifications and experience.
