Task: Answer the multiple choice question.
Query: Which compound has a 8.786\% human ether-à-go-go related gene (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] c1ccc2c(c1)[nH]c1c(N3CCCCC3)ncnc12
[b] COc1cccc(/C=N/N2CCN(C3c4ccccc4-c4ccccc43)CC2)c1O
[c] O=C(NCC(c1cccs1)N1CCOCC1)c1cc(Cl)ccc1[N+](=O)[O-]
[d] CCc1ccc(/C=C2/SC(N3CCOCC3)=NC2=O)cc1
[e] COc1ccccc1OCC(=O)OC/C(O)=C(\C#N)c1nc2ccccc2[nH]1
Answer: b. COc1cccc(/C=N/N2CCN(C3c4ccccc4-c4ccccc43)CC2)c1O
