Doctor: Angiotensinogen is a protein in human blood. Typically, the higher a person's angiotensinogen levels are, the higher that person's blood pressure is. Disease X usually causes an increase in angiotensinogen levels. Therefore, disease X must be a cause of high blood pressure.
The doctor's argument is most vulnerable to criticism on which one of the following grounds?
A. It confuses a necessary condition for a sufficient condition.
B. It overlooks the possibility that even if a condition causally contributes to a given effect, other factors may fully counteract that effect in the presence of that condition.
C. It illicitly infers, solely on the basis of two phenomena being correlated, that one causally contributes to the other.
D. It confuses one phenomenon's causing a second with the second phenomenon's causing the first.
E. It takes for granted that if one phenomenon often causes a second phenomenon and that second phenomenon often causes a third phenomenon, then the first phenomenon cannot ever be the immediate cause of the third.

LSAT 2017 CR Question
How do you generally approach such questions? When I approach it like any other CR question, the moment I start going through the options I get really confused and not only did I miss the correct answer, I took a ton of time analysing each option.
What's the most optimal way to approach this question?

The doctor's argument is most vulnerable to criticism on which one of the following grounds?
A. It confuses a necessary condition for a sufficient condition. - WRONG. Causality is what is the core of the passage here. Neither of the condition we can be sure about. It is as if X is definitely rewuired but first we should be confirmed about whether it is solely required or other factors too are required.
B. It overlooks the possibility that even if a condition causally contributes to a given effect, other factors may fully counteract that effect in the presence of that condition. - WRONG. Counteract is actually opposite to what we are looking for here. Overlooking is still fine.
C. It illicitly infers, solely on the basis of two phenomena being correlated, that one causally contributes to the other. - CORRECT. It simply assumes that A leads to C when B leads to C and A leads to B is the condition laid down already. But A leading to C is casual approach if nothing else is considered.
D. It confuses one phenomenon's causing a second with the second phenomenon's causing the first. - WRONG. Nothing like that is said.
E. It takes for granted that if one phenomenon often causes a second phenomenon and that second phenomenon often causes a third phenomenon, then the first phenomenon cannot ever be the immediate cause of the third. - WRONG. Taking granted is fine. But that is for considering the A to be the cause of C with such casual approach. But this choice says the approach was casual for A being not the causeo fC ever which is opposite to what passage dida actually.
Here's my take. Got it right.
Simply put it says that
more ATSG ----> high BP
Now,
X ----> more ATSG
From there it derived.
X ----> more BP
So, it does not consider anything else that may have played any role.
Answer C.

A. The argument does not confuse a necessary condition for a sufficient condition. It assumes a causal relationship based on correlation, not conditional logic.
B. The possibility that other factors may counteract the effect of disease X on blood pressure is not addressed in the argument. The flaw lies in assuming causation from correlation, not in overlooking counteracting factors.
D. The argument does not confuse the direction of causality between phenomena. It assumes that higher angiotensinogen levels cause high blood pressure, not the other way around.
E. The argument does not involve a chain of causality where one phenomenon leads to another, which then leads to a third. It incorrectly assumes a direct causal link between disease X and high blood pressure.
