For some years health authorities have believed that people with high blood pressure (hypertension) should restrict their salt intake. Recently scientists found in a large, well-designed study that those with chronic hypertension consume less salt than do, their counterparts with normal blood pressure.
If it is true that a diet relatively high in salt is causally linked to the onset of hypertension, which of the following, if true, most plausibly accounts for the new findings?
(A) Only a minority of those with hypertension have been properly diagnosed.
(B) Chronic hypertension is not a serious problem in the population studied.
(C) Most people with chronic hypertension have intentionally restricted their salt intake.
(D) Hypertension occurs most frequently in those who have a family history of hypertension.
(E) Excess salt intake is inh~rently dangerous to health.

In the argument, there are two findings - 1 ) general believe - health authorities have believed that people with high blood pressure (hypertension) should restrict their salt intake
2) new finding - Scientist found that those with chronic hypertension consume less salt than do others.
Question is which of the below accounts for the NEW finding ??
Pre-analysis - Maybe patients or individual might have taken precautionary measure and reduced the salt intake prior to consulting doctors.
(A) Only a minority of those with hypertension have been properly diagnosed. --> No, it doesn't match.
(B) Chronic hypertension is not a serious problem in the population studied. --> No.
(C) Most people with chronic hypertension have intentionally restricted their salt intake. --> Yes. It is correct.
(D) Hypertension occurs most frequently in those who have a family history of hypertension. --> No. Also note that if we are bringing outside knowledge, we might choose this as answer.
(E) Excess salt intake is inh~rently dangerous to health. --> No.
