• A. \( \text{Indolo [4,3-f]quinoline} \)
• B. \( \text{Indoloquinazoline} \)
• C. \(\beta\text{-Carboline}\)
• D. \( \text{Indolonaphthalene} \)

Answer 1

The Correct Option is A

Ergoline features the indolo [4,3-f]quinoline ring system, a fused bicyclic structure with indole and quinoline components. It is found in ergot alkaloids, used in treatments for migraines and Parkinson's disease. This unique structure contributes to its pharmacological activity in neurological disorders.
