Which one of the following statements is accurate?

Deploying Cloud Functions directly from a Google Cloud Source Repository is a straightforward process, making this statement accurate. Google Cloud offers integration with Cloud Source Repositories, allowing developers to automatically trigger deployments of their Cloud Functions whenever they push changes to their repository. This capability streamlines the development process and promotes continuous integration and continuous delivery (CI/CD) practices.

In contrast, the other options do not accurately describe the requirements or capabilities of Google Cloud Functions. For example, logging in Cloud Functions is enabled by default, so there is no need to manually set a flag like console.log = true. Additionally, while dependencies are managed, you don't have to package them manually in a package.zip file; Cloud Functions can automatically recognize and install dependencies listed in a configuration file like package.json in Node.js environments. Finally, Cloud Functions run in a serverless environment and are separate from App Engine, which has its own set of environments (standard and flexible). Therefore, Cloud Functions cannot run directly in the App Engine flexible environment.
