{'married couple': [0, 0, 1, 0], 'husband': [0, 3, 2, 1], 'professor': [0, 0, 1, 2], 'lawyer': [0, 0, 2, 0], 'unmarried ladies': [0, 0, 1, 0], 'doctor': [0, 1, 3, 2], 'group': [0, 1, 0, 0]}

The question provides a series of facts about a group of five people. From the information, we know that A and D are unmarried and do not work, which implies they can`t be the professor, doctor or lawyer. E is married but not specified to any profession. Regarding B, it`s clear that he is not a doctor or a lawyer; considering he does work(as he is not stated to be unemployed), he must be the professor. As for C, no specific information is given; they could be either the doctor or lawyer. Therefore, based on the given information, option 1, B is the correct answer, as he is the only one who can be the professor.
