To ensure apps are not potentially harmful, a Google engineer rigorously tests each one before it is listed on Google Play. Select the correct answer, then submit.

False. While Google employs automated systems and a team of engineers to scan for malware and policy violations, it's not feasible for a Google engineer to rigorously test each app individually before it's listed on Google Play. The sheer volume of apps submitted daily makes this impossible. Google Play relies heavily on automated checks, developer self-attestation, and user reporting to maintain app quality and security. Therefore, the statement that a Google engineer rigorously tests each app is incorrect.
