The correct answer is C. Problem and solution
Explanation:
In texts, the organizational structure refers to the way details and information in a text are organized which is also linked to the type of content included. In the case of problem and solution organization, this occurs when a text first includes a problem and then provides one or more solutions to solve it. This type of organization is the one used in the passage as this mainly begins with a problem "My best friend is allergic to dogs but really wants to adopt one" and then three conclusions are provided the first one is to get allergy shots, the second one is to get a dog with shorter hair and the third one is to buy a fish.
