Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.607\% 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: CC1(OC(=O)C2CCCC2)C(=O)C=C2C=C(c3ccsc3)N(Cc3ccc4c(c3)OCO4)C=C2C1=O
b: Cc1cc(Nc2ccc(Cl)cc2)n(-c2cccc(Cl)c2)n1
c: O=C(NCCN1CCOCC1)c1ccc(Cl)nc1
d: Clc1ccc(COC(Cn2ccnc2)c2ccc(Cl)cc2Cl)cc1.O=[N+]([O-])O
Answer: c. O=C(NCCN1CCOCC1)c1ccc(Cl)nc1
