Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.480\% 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: COc1ccc(OC)c(CNn2c(-c3cccc(C)c3)nc3ccccc3c2=O)c1
b: CCOc1ccc(NC(=O)CCN2CCN(S(=O)(=O)c3ccc(Cl)cc3)CC2)cc1
c: O=C(Nc1ccccc1)NN1CC(=O)N(c2ccc(Cl)cc2)CC1=O
Answer: b. CCOc1ccc(NC(=O)CCN2CCN(S(=O)(=O)c3ccc(Cl)cc3)CC2)cc1
