Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.860\% 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 additional words.
Options:
[a] CC(=O)Nc1ccc(NC(=O)CN(c2ccc([N+](=O)[O-])cc2)S(=O)(=O)c2ccccc2)cc1
[b] O=C(c1cc2cc(Br)ccc2o1)N1CCOCC1
[c] O=C(NCCN1C(=O)S/C(=C\c2ccc(F)cc2)C1=O)C1CCN(S(=O)(=O)c2cccs2)CC1
[d] CC1(C)C2CC=C(/C=N/NC(=O)c3ccccc3O)C1C2
[e] COCc1c(C#N)c(NCCc2ccc(F)cc2)nc(C)c1[N+](=O)[O-]
Answer: b. O=C(c1cc2cc(Br)ccc2o1)N1CCOCC1
