Task: Answer the multiple-choice question.
Query: Which drug has a 10.159\% 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) O=C(O)/C=C/c1ccc(OCc2cccc(F)c2)cc1
(b) C[C@H](N[C@@H](CCc1ccccc1)C(=O)O)C(=O)N1CCC[C@H]1C(=O)O
(c) O=C(CCC(=O)OCC(F)(F)C(F)F)Nc1ccc(Cl)cc1
(d) Cc1ccc(CSc2nnnn2C)cc1
Answer: b. C[C@H](N[C@@H](CCc1ccccc1)C(=O)O)C(=O)N1CCC[C@H]1C(=O)O
