   A CI/CD pipeline for a web application fails during the test stage. The test report shows that a unit test for the login functionality failed. The test was passing locally. The pipeline runs tests in a Docker container with a clean environment. The test relies on a local database that is seeded with test data. What is the most likely cause of the test failure?

   • AThe test framework version is different in the pipeline than locally.
   • BThe Docker container does not have the test database seeded, so the test fails due to missing data.
   • CThe test is flaky and fails intermittently due to timing issues.
   • DThe test code has a hardcoded path that only works on the developer's machine.

What is the most likely cause of this failure?

   • AThe build environment is using the wrong Python version.
   • BThe requirements.txt file has a syntax error.
   • CThe dependency version is not specified in requirements.txt.
   • DThe private PyPI server is not accessible from the build environment.
