Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -13.587\% 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=C1CC(=O)Nc2cc(S(=O)(=O)N3CCN(c4ccc([N+](=O)[O-])cc4)CC3)ccc2N1
b O=C(Nc1ccc(Cl)c(Cl)c1)c1ccc(Cn2c(=O)[nH]c3ccsc3c2=O)cc1
c CCOC(=O)CC(=O)NC1(Cc2ccc(O)cc2)CCCCC1
d O=C(CNC(=O)C12CC3CC(CC(C3)C1)C2)NC1=NCCS1
Answer: a. O=C1CC(=O)Nc2cc(S(=O)(=O)N3CCN(c4ccc([N+](=O)[O-])cc4)CC3)ccc2N1
