Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.257\% 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) Cc1ncsc1CCC(=O)N1CCCC(Nc2ccc(C(C)C)cc2)C1
(b) O=C(Oc1ccccc1Cl)c1ccccc1P(=O)(O)O
(c) CC1=C(C(=O)OCc2ccccc2)C(c2ccc([N+](=O)[O-])cc2)NC(=O)N1CCCCCC(=O)O
Answer: b. O=C(Oc1ccccc1Cl)c1ccccc1P(=O)(O)O
