Task: Answer the multiple choice question.
Query: Which drug has a 17.209\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(C2N(C(=O)N3CCOCC3)CCN2S(=O)(=O)c2ccc(C)cc2)cc1
b O=C1NC(=S)N/C1=C/c1cc2c(cc1[N+](=O)[O-])OCO2
c O=C(COC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1)Nc1ccc(Cl)cc1
d COc1ccc(S(=O)(=O)N2CCCCCC2)cc1NC(=O)Cc1ccccc1
Answer: b. O=C1NC(=S)N/C1=C/c1cc2c(cc1[N+](=O)[O-])OCO2
