If someone has a health problem and I would like to ask him/her what the cause of the problem is, two questions are in my mind:
- Is it due to eating unhealthy food?
- Is it due to not playing sport?
Now I need to use the word or or something like that to ask the two questions at the same time. How can I do it to sound like a native speaker? And which of the following is correct?
- Is it due to eating unhealthy food or not playing sport?
- Is it due to eating unhealthy food or is it due to not playing sport?
- Is it due to eating unhealthy food or it is due to not playing sport?
Thank you,
