Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -0.741% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C1CC(c2ccccc2)Cc2nc(NC3CC3)ncc21
b: CCOC(=O)c1c(C)n(-c2ccc(OC)cc2)c2c(C/C(C)=N/O)c(Br)c(OC)c(O)c12
c: O=C(CCC(=O)Nc1ccccc1Cl)NNC(=O)Nc1cccc([N+](=O)[O-])c1
d: CCOC(=O)CCCCC(=O)c1[nH]c(=O)[nH]c1CSCCO
e: COc1ccc(S(=O)(=O)N2CCCC(C(=O)NCc3ccccn3)C2)cc1Cl
Answer: c. O=C(CCC(=O)Nc1ccccc1Cl)NNC(=O)Nc1cccc([N+](=O)[O-])c1
