Task: Answer the multiple choice question.
Question: Which compound has a 12.513\% 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 O=C(CSC1CC(=O)N(CC(c2ccccc2)c2ccccc2)C1=O)Nc1ccc(Cl)cc1
b O=c1ccn([C@@H]2O[C@H](CO)[C@@H](O)[C@H]2O)c(=O)[nH]1
c CCOc1ccccc1CNc1nc2nc3c(c(=O)n2[nH]1)CCC3
Answer: b. O=c1ccn([C@@H]2O[C@H](CO)[C@@H](O)[C@H]2O)c(=O)[nH]1
