Idiopathic describes no known cause. Which option contains the term that matches this definition?

Explanation:
Idiopathic means a disease or condition with no identifiable cause. That exact idea—no known cause—is what this term conveys, so it fits the definition best. Endogenous refers to factors arising from within the body, exogenous to factors from outside the body, and iatrogenic to problems caused by medical treatment. These describe origins or sources, not the absence of a known cause, which is why they don’t match the definition as closely as idiopathic.
