Task: Answer the multiple choice question.
Question: Which compound exhibits a -10.447% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(N2CCN(S(=O)(=O)c3ccc(C(=O)NC4CCCC4)cc3)CC2)cc1
b: CC[C@@H](C)[C@H](CN[C@H](CNC)C(C)C)NC[C@@H](C)c1ccc(CC(C)C)cc1
c: O=C(OC1CCCCC1)c1cc2ccccc2oc1=O
Answer: b. CC[C@@H](C)[C@H](CN[C@H](CNC)C(C)C)NC[C@@H](C)c1ccc(CC(C)C)cc1
