D) In a recent media story, a professor (not yours!) was quoted saying, "ironically, if the coronavirus continues to spread, companies may try to accelerate theautomation of some jobs(Links to an external site.)

so they don't have to depend on workers" -- use labor demand theory to justify or counter this statement.
