Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.547\% 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 other words.
Options:
a: COc1cc(C(=O)OC2CCCCC2=O)cc(OC)c1C
b: C[C@H](O)C(=O)C1=Nc2c(nc(N)[nH]c2=O)NC1
c: CCCNC(=O)[C@@H]1CCCN1C(=O)[C@@H]1Cc2ccccc2CN1.Cl
Answer: b. C[C@H](O)C(=O)C1=Nc2c(nc(N)[nH]c2=O)NC1
