Which statement correctly describes running Yeoman's Doctor?

• A. It diagnoses the configuration of Node, npm, Git, and JDK to ensure Yeoman runs smoothly.
• B. It publishes a generator to npm.
• C. It scaffolds a new project automatically.
• D. It runs unit tests for generators.

Answer: (A)

Yeoman Doctor checks your development environment to ensure essential tools are installed and configured so Yeoman can run reliably. It specifically verifies Node.js, npm, Git, and the Java Development Kit (JDK), reporting any issues or misconfigurations and guiding you to fix them. This is why the statement that best describes it is that it diagnoses the configuration of Node, npm, Git, and JDK to keep Yeoman running smoothly. The other options describe actions handled by other parts of the toolchain—publishing a generator to npm, scaffolding a project, or running unit tests for generators—not what Doctor does.
