yes it is C .. but being submerged isn't just sufficient.. being submerged in a well oxygenated water would be a more precise answer.. – WYSIWYG Nov 14 '13 at 11:30
Do you want to answer this question yourself with some justification on why you think it is C – WYSIWYG Dec 9 '14 at 6:11

I think the answer should be C because when it is submerged, cutaneous respiration takes place and hence right atrium receives more oxygenated blood.
