Let's look at the Argument
There is person named Vishal, he has High BP issue and also he is more nervous and anxious, in comparison to Rishi who has normal blood pressure and not that much nervous and anxious. Based on this fact author concluded that nervousness and anxiousness caused high BP to Vishal.
Since we have to find a flaw in the reasoning of author.
Just on the fact that two things are correlated, he concluded that
A caused B, it may be the case that B cause A or there is C which caused B or C caused both A and B.
By looking at this analysis D perfectly matches the flaw.
A. It is not the flaw. This is defined already
B. No presupposition done
C. Claim is Hypersensitivity causes High BP. So incorrect
E. Othe personality trait has in person with high BP not a point. The conclusion can still be true so incorrect
Bunuel
People with high blood pressure are generally more nervous and anxious than people who do not have high blood pressure. This fact show that this particular combination of personality traits—the so-called hypertensive personality—is likely to cause a person with these traits to develop high blood pressure.
The reasoning in the argument is most vulnerable to criticism on the grounds that the argument
A. fails to define the term “hypertensive personality”
B. presupposes that people have permanent personality traits
C. simply restates the claim that there is a “hypertensive personality” without providing evidence to support that claim.
D. takes a correlation between personality traits and high blood pressure as proof that the traits cause high blood pressure.
E. focuses on nervousness and anxiety only, ignoring other personality traits that people with high blood pressure might have
