The first alternative is correct (A).
From the information that the house has its messy exterior, among the alternatives proposed, the most appropriate is the one that owners do not like to clean the house.
Although there are other reasons why a house may be messy, the issue eliminates other possibilities because it is a matter of inference.
In this way, it is not possible to say, for example, that they have children or dogs, or that the amount of floors. Nor do we have information about other houses.
The answer must be given only with information: the house is messed up on the outside.
So we infer that the house has the messy exterior because the owners do not like to clean the yard, which is usually common.
