Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.919\% 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=N/Nc2nc(=O)[nH]nc2C)cc([N+](=O)[O-])c1O
[b] O=C(Nc1cccc(Cl)c1)c1cc(S(=O)(=O)N2CCOCC2)cs1
[c] CSCC[C@H](NC(=O)OC(C)(C)C)C(=O)N1CCC(C(=O)N[C@H](C(=O)O)C(C)C)CC1
Answer: b. O=C(Nc1cccc(Cl)c1)c1cc(S(=O)(=O)N2CCOCC2)cs1
