Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.571\% 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: COc1ccc(C2=C(c3ccc(OC)cc3)N3CCS(=O)(=O)N=C3S2)cc1
b: CNC(=O)c1ccccc1NC(=O)c1ccc(C)c(S(=O)(=O)N2CCCCC2)c1
c: COCCn1c(=NC(=O)CCS(=O)(=O)c2ccccc2)sc2ccccc21
d: O=C1NC(=O)C(=Cc2ccc(-c3ccccc3[N+](=O)[O-])o2)C(=O)N1
Answer: c. COCCn1c(=NC(=O)CCS(=O)(=O)c2ccccc2)sc2ccccc21
