The correct answer is: Jalan’s team is able to complete frequent product releases without the introduction of new bugs by using continuous integration; it is embedded into the release to make sure no new bugs are being introduced. The
other responses are incorrect because manual testers don’t need to be involved; it would be burdensome on testing resources if releases are frequent, which could be numerous times a day. In addition, regression testing is time-consuming
and not a good choice for frequent releases; pair programming is focused more on continuous integration than bugs.
