Task: Answer the multiple choice question.
Question: Which drug has a 2.641\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] C/C(=N\NC(=O)c1ccc(Cl)cc1)c1cccc(NC(=O)c2cccnc2)c1
[b] COc1cccc(OCc2cc(/C=N/NC(=O)c3ccn[nH]3)ccc2OC)c1
[c] COc1ccc(NC(=O)Cn2c3ccc(OC)cc3c3nc4n(c(=O)c32)CCS4)cc1
[d] CC1=CCC2COC(c3ccc[n+](Cc4ccccc4)c3)C1C2.[Cl-]
Answer: a. C/C(=N\NC(=O)c1ccc(Cl)cc1)c1cccc(NC(=O)c2cccnc2)c1
