As a DevOps engineer, you are developing a composite action.

For a composite action, commands are defined inside the runs.steps section of the action metadata file. When a specific command must execute from a particular folder, the correct key is working-directory, and it must be applied at the individual run step level. Option D is correct because it keeps using: " composite " at the runs level and applies working-directory: ${{ inputs.dir }} directly to the step that runs the script. Option A is incorrect because directory is not a valid GitHub Actions run-step key. Option B incorrectly places directory at the runs level. Option C uses the right keyword but places it at the wrong level. This tests composite action metadata syntax and correct step-level execution configuration.
