Upon acquiring a new computer operating system, management at Fox Co. worried that computer virus might cripple the company's operation. Management decided to install anti-virus software and to build a firewall for its operating system. Fox Co. chose to reduce the risk of being crippled by computer virus.
The most appropriate answer is: b) reduce.
While "avoid" might seem tempting, it's virtually impossible to eliminate all computer virus risks entirely. "Share" and "accept" are clearly incorrect as they don't address Fox Co.'s proactive measures to mitigate the threat.
By installing anti-virus software and building a firewall, Fox Co. is actively taking steps to minimize the potential damage of a computer virus, not eliminate it entirely. They are reducing the risk, making it the most accurate choice.
Therefore, the correct answer is b) reduce.
