Well, a triglyceride is made of glycerol and 3 fatty acids to form a tri-ester, so you have the glycerol molecule bonding with 3 fatty acids forming 3 esters bonds. An ester bond is RCOOR', and as you form 3 of these ester bonds, your molecule will have 6 oxygens over all, so M is the answer. N has far too many oxygens to be a triglyceride.
