Hi,
Everything applies. It is impossible to predict based on the current data. All scenarios are possible with equal possibility.
Hope this helps.

Answer: David is most likely playing on Handheld.
Explanation: You can infer that he is playing on a handheld due to the fact that he is playing this game on his way to work, and the fact that he is controlling the game using an analog stick. Because of this, you can assume that what he is playing on needs to be portable, making it likely he is using a handheld.
I'm pretty sure you would use A.) Quotation Marks.
Hope I helped!
