Task: Answer the multiple choice question.
Question: Which drug has a 20.465\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cl.Fc1ccc(Nc2ncnc3ccccc23)cc1
[b] CCOC(=O)c1ccc(NC(=O)c2nc[nH]c2C(=O)N[C@@H](C)C(=O)OC(C)(C)C)cc1
[c] O=C(O)c1nn(CCOc2ccc(Cl)cc2Cl)c(=O)c2ccccc12
Answer: c. O=C(O)c1nn(CCOc2ccc(Cl)cc2Cl)c(=O)c2ccccc12
