Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.633\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(NNC(=O)c1ccccc1O)c1ccc(NS(=O)(=O)c2ccc(F)cc2)cc1
(b) CCc1ccc(C(C)NC(=O)C2CCCO2)cc1
(c) COc1ccc(CNc2nc(NCc3ccc(OC)cc3)n(C(=O)c3ccccc3[N+](=O)[O-])n2)cc1
(d) COCc1c(C(=O)Nc2ccc(Cl)cc2F)oc2ccccc12
Answer: b. CCc1ccc(C(C)NC(=O)C2CCCO2)cc1
