Pull requests (PRs) on GitHub can have several statuses that indicate their current state in the development and review process:

Draft:

Option A is correct. A pull request can be in a "Draft" status, indicating that it is a work in progress and not yet ready for review.

Closed:

Option B is correct. A pull request can be "Closed" without being merged, which might happen if the proposed changes are not needed or are incorporated differently.

Merged:

Option D is correct. A pull request that has been reviewed and approved can be "Merged" into the target branch, indicating that the changes have been successfully incorporated.

Open:

Option F is correct. An "Open" pull request is one that is active and awaiting review or further action.

Incorrect Options:

Option C (Rebasing) is incorrect because "Rebasing" is not a status; it's an operation that can be performed on branches.

Option E (Modified) is incorrect because there is no "Modified" status for pull requests.
