You may or may not know that, in addition to the option to delete/remove a question or answer option, we also have the option to disable questions and answer options. If you are aware of both you might be confused why we have these similar options. It's actually because they are quite different!
When Should I Delete/Remove a Question/Answer Option Versus Disable It?
If the question or answer option has collected data and you expect that you might want the data at a later time, we recommend disabling your question or answer option instead of deleting. By and large, if you restore a deleted question or answer option that has collected data, the data will be restored as well, but with very complex question types (I'm looking at you Custom Tables) we've run into data loss issues when a question or answer option has been deleted and restored. This is why we have the option to disable a question.
What Are the Implications of Deleting/Removing?

What Are the Implications of Disabling?
In Surveys
Disabled questions and answer options will not display for any survey responses that are started after the question has been disabled. Notice, this behavior is the same as for deleted questions.

Disabled answer options will not display on the Build tab. When editing the question you can display disabled options if you wish. To do so, click the Advanced Option Settings link above the answer options and select Show disabled options and Save.
Now your disabled answer option will appear greyed out, with the option to restore it next to the red X. Give it a click to re-enable!
