C. It turns out that workers will have greater employment opportunities if their occupation undergoes some degree of computer automation.
Explanation:
Many people fear automation, thinking that computers are taking over tasks performed by workers and that they could lead to unemployment (as stated in options A and D). But, according to James Bessen, that is incorrect. In the given paragraph he explicitly says that it turns out that workers will have greater employment opportunities if their occupation undergoes some degree of computer automation. That's good news about computer automation (option B is incorrect because this paragraph tells us about good, not bad news).
