Conditional mood, but not sure
Tired, and possibly dehydrated.
The last sentence is correct, because the other ones either had periods in the middle or too many commas in them.
The answer would be the last one, leave it as is. B and C change the meaning of the sentence entirely, while A sounds unnatural and is too verbose.
Hope this helps! :)
