In Git, what does the command `git add <file>` do?
Commits the file's current content directly to the repository history
Marks the file to be tracked but stores no content snapshot until the commit itself runs
Records the file's current content in the index, to be included in the next commit✓Respuesta correcta
Uploads the file to the configured remote repository
Explicación
`git add` copies the file's content, as it is at that moment, into the index (staging area); the next `git commit` records what is in the index. The tempting distractor is 'marks the file to be tracked but stores no content': `git add` does start tracking new files, but it also stores an actual snapshot of the content immediately — which is why edits made after `git add` are not staged.
