What percentage of hypertension is secondary?

Explanation:
Secondary hypertension is hypertension caused by an identifiable underlying condition or external factor. In adults, only about five percent of hypertension cases are secondary; the vast majority (roughly 95%) are essential (primary) hypertension with no single identifiable cause. That’s why five percent is the best answer. The other options overstate or misstate the proportion: ninety-five percent would imply almost all cases are secondary, which isn’t true; fifty percent isn’t supported; zero percent would mean none are secondary, which is also incorrect.
