The premise is about a CORRELATION:
A combination of nervousness and anxiety has been OBSERVED in people with high blood pressure.
The conclusion is about CAUSATION:
A combination of nervousness and anxiety CAUSES high blood pressure.

The argument incorrectly assumes that a CORRELATION is sufficient to prove CAUSATION.
D correctly describes this flaw:
The argument takes a correlation between personality traits and high blood pressure as proof that the traits cause high blood pressure.

The correct answer is D.

E: The argument focuses on nervousness and anxiety only, ignoring other personality traits that people with high blood pressure might have.
This option implies the following:
It is a flaw not to consider EVERY TRAIT that people with high blood pressure might have.
This expectation is unreasonable.
It is not possible for an argument to consider EVERY POSSIBLE TRAIT.
Eliminate E.
