Answer:
This is an example of C. testimonial evidence.
Step-by-step explanation:
Testimonial evidence does exactly what it implies. It testifies to a main point or argument.
In this case, the statement being proposed is below:
"The strict regimentation at fast food restaurants creates standardized products. It increases the throughput. And it gives fast-food companies an enormous amount of power over their employees. "
And the testimonial is what sociologist, Robin Leider, writes below:
" 'When management determines exactly how every task is to be done . . . and can impose its own rules about pace, output, quality, and technique,' "
&
" '[it] makes workers increasingly interchangeable.' "
