I believe the answer is d, but don't quote me on that.
Hello. You did not enter the text to which the question refers, nor did you show the title of the text which makes it impossible for your question to be answered. However, I can help you by showing you how to find the information you need to find the answer you need in the text you have.
First, you must understand that the term "inferencia" refers to a deduction that you can make based on certain information expressed in the text, that is, the text passed on information about the news media, how it works and how it is influential in our world. This information will lead you to make a deduction, create a thought that you think is correct, about the news media. This is the inferences you must find.
For example: The text says that the news media has invested in exaggerated news of major tragedies such as theft, murder and torture, rather than passing on really relevant and informative news to the population. From this information you can make the inference: The current media is sensational.
That would be an example of a case study.
Case studies are in-depth, highly specialized and detailed examinations of a certain problem. This is a really up close research method that studies, examines the case that is the subject of examination. Case studies are the usual thing to do in this situation and they are of immense value to their field but are not generally represented in more popular works mainly because they require a high knowledge of the field and the problem within a particular field.
