Outsourcing has been particularly detrimental to employment in which american industries?
a. manufacturing and customer service
b. health care and dental care
c. agriculture and food processing
d. research and development

I would say the answer is A

A. manufacturing and customer service

Explanation:

    Manufacturing and service outsourcing has raised some ethical issues in companies. Many of them have criticized this practice because of its impact on workers.

    In general, employees of companies that often outsource staff see this as a threat to their jobs. This creates a lot of insecurity and sometimes ends up negatively impacting productivity.

    Unfortunately, in many cases, this insecurity is justified as registered employees actually lose their job to outsourced individuals. This is especially so because these individuals often earn lower wages to perform the same function as the contractor.
