Task: Answer the multiple choice question.
Question: Which drug has a 8.589\% 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: c1ccc(Cc2nnc(N3CCCCC3)c3ccccc23)cc1
b: CSCC[C@H](NC=O)C(=O)N[C@@H](CC(C)C)C(=O)N[C@@H](Cc1ccccc1)C(=O)O
c: CSc1nnc(NC(=O)c2nc(S(=O)(=O)Cc3cccc(C)c3)ncc2Cl)s1
d: CCOP(=O)(OCC)C(NS(=O)(=O)c1ccccc1)C(Cl)(Cl)Cl
Answer: b. CSCC[C@H](NC=O)C(=O)N[C@@H](CC(C)C)C(=O)N[C@@H](Cc1ccccc1)C(=O)O
