Task: Answer the multiple choice question.
Query: Which compound has a 13.223\% 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 CCOC(=O)/C(C#N)=C/c1c(Oc2cc(C)cc(C)c2)nc2ccccn2c1=O
b N=c1nc(N2CCCCC2)cc(N)n1O
c O=C(CSc1nnc(-c2cccs2)o1)N1CCc2ccccc21
d CC1=C[C@@H]2c3cccc4[nH]cc(c34)C[C@H]2N(C)C1
e CCOC(=O)C/C(C)=N/NC(=O)c1cccs1
Answer: b. N=c1nc(N2CCCCC2)cc(N)n1O
