Many companies that sell computer software are trying to increase the productivity of their programmers, measured by the lines of code written in one day by a programmer. One method attempted by some companies is to let programmers work from home. Programmers who work from home do not need to commute to and from work and can therefore spend more of the day writing code. Therefore, companies that allow their programmers to work from home will see a corresponding increase in the productivity of those programmers.

Which of the following, if true, most strengthens the argument?

A. Before the advent of virtual private network technology, working outside of the office presented security risks unacceptable to most companies.

B. Programmers write more effective code when they are able to work in a comfortable environment.

C. Companies that allow employees to work from home can see reductions in certain expenses, such as electricity and building upkeep.

D. Most older companies oppose allowing employees to work from home, whereas most newer companies support employees working from home.

E. The number of lines of code a programmer writes per hour is relatively constant.
