The other answer choices are incorrect for the following reasons:

• The house agent asked Mr. Barrington what sort of a house would he be looking for. - This is incorrect because the modal verb "would" in the reported speech is used to express possibility or speculation, but the original sentence is a simple question about what sort of house Mr. Barrington is looking for.
