The answer should be none of these.
Mario can never catch the ghost.
The best way for Mario to try and catch him would be to open the same door everyday so that the ghost may come at that particular room and Mario would catch him. But this can't happen as the ghost may keep moving to two adjacent rooms back and forth instead of going either only forward or only backward.
For example:
Mario opens door 5 everyday, but the ghost may keep moving from 7 to 8 then back to 7 then back to 8 and so on.
This way, Mario will never be able to catch him.
Hence the answer would be none of these.

Answer is 10 as each day he will open the same door and hence after ten days he will catch the ghost

Ok Ayush
When you check 2 I'm in 1.... Similarly when you check 8 I'm in 7.
When you check 9 I'm in 8.
Now that you'll start going back, it doesn't mean I'll continue forward.
So, now when you check 8, I'm back in 7, because adjacent doesn't only mean the next room, it can be the previous room as well.
Now going back, when you check 2 I'm in 1. Again you check 3 and I'm in 2.
So there's no guarantee that you'll be able to catch me.
Hence answer is none of these.
