   A Python project uses pip and has a requirements.txt file. The team wants to separate production dependencies from development-only tools like pytest and black. They also want to ensure that the production environment does not install development tools. What is the best approach?

   • ACreate a requirements-dev.txt that includes '-r requirements.txt' and lists the dev tools
   • BUse pip freeze to generate a requirements.txt that includes only the packages needed at runtime
   • CCreate a separate virtual environment for development and install all packages there, leaving requirements.txt empty
   • DPut all dependencies in requirements.txt and use pip's --no-dev flag during production installs

   A Java application uses Maven. It has a direct dependency on library X version 1.0.0, which transitively depends on library Y version 2.0.0. The application also has a direct dependency on library Z version 3.0.0, which transitively depends on library Y version 1.5.0. The application code uses a class from Y that was removed in version 2.0.0. The build succeeds, but at runtime a ClassNotFoundException occurs. What is the most likely cause and the best fix?

   • AMaven selected Y 2.0.0 because X is declared before Z; add an explicit dependency on Y 1.5.0
   • BMaven failed to resolve the conflict, so the build should have failed; run 'mvn dependency:tree' and force Y 1.5.0
   • CMaven selected Y 1.5.0 because Z is declared after X; exclude Y from Z
   • DThe application should declare Y as a provided-scope dependency to ensure the correct version is used at runtime

   • BRemove the function in the next minor release and document it in the changelog
   • CDeprecate the function in the next minor release and remove it in the next major release
   • DRemove the function in the next patch release to keep the version number low
