Task: Answer the multiple choice question.
Query: Which compound exhibits a -27.978\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(CN1C(=O)C2CCCCN2C(=O)c2ccccc21)N1CCCc2ccccc21
b: CC(C)C[C@H]1CN=C(N(C)C)N1CCCCc1ccccc1
c: Cc1ccc(NC(=O)c2cc(S(=O)(=O)N(C)C)ccc2N2CCCC2)cc1S(=O)(=O)N(C)C
Answer: b. CC(C)C[C@H]1CN=C(N(C)C)N1CCCCc1ccccc1
