Question: A husband and a wife were chronic alcoholics. One afternoon, the husband drank a fifth of bourbon and was drunk when his wife returned home from work. When the wife saw her husband's condition, she got very angry because they had planned to go out to dinner and celebrate their wedding anniversary. While the husband was passed out on the living room couch, the wife decided to fix herself a martini. After drinking two martinis, the wife became extremely inebriated. A short while later, the wife began preparing a third martini and tried to slice a lemon for the drink. As she did so, the knife slipped, and she cut her hand severely. With blood gushing from the wound, the wife called her husband to help her. He awoke momentarily, stood up, but fell back on the couch and passed out. He failed to render any assistance, and the wife bled to death. If the husband is subsequently charged with manslaughter, he will be found
A: guilty, because he owed his wife a duty to assist her. 
B: guilty, because criminal negligent conduct cannot be negated by voluntary intoxication. 
C: not guilty, because the wife caused her own injury. 
D: not guilty, because he was physically unable to assist her. 
Please eliminate two incorrect options first, then think it step by step and choose the most proper one option. The response should be in all capital letters.
