Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.424\% 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 other words.
Options:
[a] CC(=O)N(C)C1=C(N2CCOCC2)C(=O)c2ccccc2C1=O
[b] O=C(C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCCCCO)O1)N1CCOCC1
[c] CCOC(=O)N1CCN(S(=O)(=O)c2ccc3[nH]c(=O)oc3c2)CC1
Answer: b. O=C(C1=C[C@H](c2ccc3c(c2)OCO3)C[C@H](OCCCCO)O1)N1CCOCC1
