Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.551\% 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.) O=C(COc1ccccc1[N+](=O)[O-])Nc1cc(Cl)ccc1C(=O)O
b.) O=C1NN(c2ccccc2)C(=O)/C1=C/c1ccc(Sc2cccc3ccccc23)o1
c.) O=C(Nc1ccc2c(c1)CCC2)C1CCN(c2c3c(nc4ncnn24)CCC3)CC1
Answer: b. O=C1NN(c2ccccc2)C(=O)/C1=C/c1ccc(Sc2cccc3ccccc23)o1
