Task: Answer the multiple-choice question.
Query: Which compound exhibits a -26.884% 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 other words.
Options:
a) COc1nc(-c2ccccc2)c2c(c1C#N)CC(C)(C)OC2
b) O=C(COC(=O)CCNS(=O)(=O)c1cccs1)Nc1cc(C(F)(F)F)ccc1Cl
c) CC1CN(c2ccc([N+](=O)[O-])c(NCCOc3ccccc3)c2)CC(C)N1
d) O=c1cc(NCc2ccc3c(c2)OCO3)[nH]c(=O)n1-c1ccc(Cl)cc1
e) Cn1c(=O)c2[nH]c(NCCCN3CCOCC3)nc2n(C)c1=O
Answer: c. CC1CN(c2ccc([N+](=O)[O-])c(NCCOc3ccccc3)c2)CC(C)N1
