Task: Answer the MCQ question.
Question: Which drug exhibits a 19.917\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1ccc(-c2cc(C(F)(F)F)nc(SCC(N)=O)n2)cc1
(b) O=C(CNC(=O)c1ccc(Br)o1)NCc1ccc2c(c1)OCO2
(c) O=C(O)C1CN(C(=O)c2cccc(Br)c2)C1
Answer: c. O=C(O)C1CN(C(=O)c2cccc(Br)c2)C1
