The correct answer is: A hawker goes from house to house.

A hawker is a person who sells goods or services from a portable stall or table, typically on the street. They often go from house to house, selling their wares to people who are at home.

The other options are incorrect because they do not accurately describe the way that a hawker typically travels. Option B, “from, at,” is incorrect because a hawker does not typically stay at one house. Option C, “by, to,” is incorrect because a hawker does not typically travel by car or other vehicle. Option D, “to, to,” is incorrect because a hawker does not typically travel to the same house twice.
