Task: Answer the multiple-choice question.
Query: Which compound exhibits a 15.518\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=[N+]([O-])c1ccc(Sc2nc3ccccc3o2)c([N+](=O)[O-])c1
[b] O=C(CC1(O)C(=O)N(Cc2ccccc2)c2ccccc21)c1ccc2c(c1)OCO2
[c] CCOC(=O)C(C)/C(C)=N/NC(=O)CCC(=O)Nc1cc(C)ccc1C
Answer: b. O=C(CC1(O)C(=O)N(Cc2ccccc2)c2ccccc21)c1ccc2c(c1)OCO2
