Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.566\% 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: COc1ccc(C=O)cc1
b: CCOC(=O)c1c(NC(=O)CSc2nnc(-c3ccncc3)n2Cc2ccco2)sc(C)c1C
c: Br.N=C(N)SCc1ccc(Cl)cc1Cl
d: COc1ccc(NC(=O)C(NC(C)=O)C(=O)NCc2ccccc2Cl)cc1
e: COc1ccccc1N/C=C/C(=C(C#N)C#N)N(C)C
Answer: e. COc1ccccc1N/C=C/C(=C(C#N)C#N)N(C)C
