Task: Answer the multiple-choice question.
Question: Which drug has a -1.135\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(COc1ccc(Cl)cc1)N1CCN(c2ccc([N+](=O)[O-])c(N3CCCCC3)c2)CC1
b: CCC(=O)N1CCc2cc(S(=O)(=O)CCC(=O)NCc3ccccc3OC)ccc21
c: COc1ccc(S(=O)(=O)N2CCOC23CCN(S(=O)(=O)c2cc(F)ccc2F)CC3)cc1
d: CC1(c2nnc(Cc3ccccc3)o2)CC(c2cccc(F)c2)=NO1
e: CCN(CC)C(=O)C(=O)c1cccn1-c1ccc(C#N)cc1
Answer: e. CCN(CC)C(=O)C(=O)c1cccn1-c1ccc(C#N)cc1
