Task: Answer the multiple choice question.
Question: Which compound has a 6.467\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(CSc1nncc(=O)[nH]1)NCc1ccccc1
[b] COc1ccc(C)cc1NC(=O)C(OC(=O)c1ccc([N+](=O)[O-])o1)c1ccccc1
[c] C=CCNc1nc(N)c(C(=C(C#N)C#N)c2ccc(Br)cc2)s1
[d] COc1cc(C(=O)Nn2cnnc2)ccc1OC(F)F
[e] Cc1cc(N(C)C)c(C#N)c(N2CCCCC2)n1
Answer: e. Cc1cc(N(C)C)c(C#N)c(N2CCCCC2)n1
