Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.753\% human ether-à-go-go related gene (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) CCc1nc(N2CCN(C(=O)c3ccco3)CC2)c(C#N)c2c1COC(C)(C)C2
(b) CC(=O)Nc1ccc(S(=O)(=O)N2CCN(Cc3ccccc3[N+](=O)[O-])CC2)cc1
(c) O=C1N(c2cccc(Cl)c2)C(c2ccccc2)N2CCCN12
Answer: a. CCc1nc(N2CCN(C(=O)c3ccco3)CC2)c(C#N)c2c1COC(C)(C)C2
