Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.968\% 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] COc1cc(NC(C)CCCN)c2ncccc2c1.O=P(O)(O)O
[b] O=C(CN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccccc2F)CC1
[c] COc1ccccc1N1CCN(C(CNC(=O)c2ccco2)c2cccnc2)CC1
[d] C[C@H](NC(=O)Cn1cncn1)c1ccccc1
[e] COc1ccc(N/C(=C/[N+](=O)[O-])SC)cc1
Answer: b. O=C(CN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccccc2F)CC1
