Answer:
The weakness in the editorial is that it relies too much on Option C: irrational personal opinions.
Step-by-step explanation:
Editorials are argumentative in nature. They are usually published in journals or newspapers. They are written to address some issue which is either a recent news or an event. These texts are concise and to the point. They are not lengthy. Their main motive is to support a particular opinion on the issue.
In the given editorial, writer has given a lot of details on his personal experience. Instead of elaborating more on the problem, he has written details about his personal incident. Thus, relying too much on irrational personal opinion makes the editorial weak.
