Problem statement: Answer the multiple-choice question.
Question: Which compound has a -6.402\% 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, or d without using any additional words.
Options:
a: CCOC(=O)C1CCCN(C(=O)Cn2cccc2C(=O)c2ccccc2)C1
b: O=C(COc1ccc([N+](=O)[O-])cc1)Nc1ccc2c(c1)OCO2
c: CC(=O)OC1C(OC(C)=O)N(C(C)=O)C(=O)N1C(C)=O
d: O=C(O)c1cccc(S(=O)(=O)N2CCOCC2)c1
Answer: d. O=C(O)c1cccc(S(=O)(=O)N2CCOCC2)c1
