What percentage of seizures are idiopathic according to the common classification?

Explanation:
Seizures are classified based on whether there is an identifiable cause. Idiopathic seizures are those with no structural brain lesion or metabolic cause found, and they’re often linked to a genetic predisposition. In the common classification, these idiopathic forms make up the majority of seizure disorders—about three quarters, or roughly 75%. That’s why 75% is the best answer. The rest of seizures are due to identifiable brain pathology or other causes (symptomatic) or are cases where no cause is found despite evaluation (cryptogenic), which is why the other percentages don’t reflect the usual distribution.
