Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.193\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc2cc(C(N)=O)/c(=N\NC(=O)c3ccccc3)oc2c1
[b] Fc1ccc(-c2nc3c(-c4ccc(Cl)cc4)cnn3cc2CCN2CCOCC2)cc1
[c] COc1ccc(NC(=O)CN(C)C(=O)c2ccc(NS(=O)(=O)c3cccc([N+](=O)[O-])c3)cc2)cc1
[d] CCOC(=O)c1ccc(Nc2nc(C)cc(C)n2)cc1
Answer: c. COc1ccc(NC(=O)CN(C)C(=O)c2ccc(NS(=O)(=O)c3cccc([N+](=O)[O-])c3)cc2)cc1
