Answer Details

The most appropriate option to fill in the blank is "does he". The sentence "He does not seem to know how to solve the problem" is a statement, not a question. Therefore, the correct way to form a question from this statement is to use the auxiliary verb "does" to start the question, followed by the subject "he", and then the main verb "know". Using "does he not" would also be correct grammatically, but it sounds more formal and less commonly used in everyday conversation. "Doesn't he" is also grammatically correct, but it's less formal and more commonly used in informal conversations or spoken language. "Does not he" is not commonly used in modern English.
