Final answer:
Dave's inability to create a feature branch after deleting a Custom Object could be due to insufficient permissions, not flagging the 'Re-create Feature Branch' checkbox, or because the base branch was set to the master branch and the component was not in production. All of these could prevent the creation of a feature branch.
Step-by-step explanation:
When Dave was assigned the task of deleting a Custom Object and noticed that no feature branch was created after committing the destructive changes, there could be several reasons for this. First, it is possible that he did not have the necessary permissions to delete the component in the source org. Another possibility is that the 'Re-create Feature Branch' checkbox was not flagged, which is necessary to generate a new branch after the changes. Lastly, if the base branch was set to the master branch and the component was not in production, this could prevent the creation of a feature branch because the master branch typically reflects the production state, and non-production changes may not trigger the automatic creation of a feature branch. Without more context, it's challenging to determine the exact reason, but (d) All of the above could be valid reasons for the issue described.
