Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.618\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CCCOC1CCCN(Cc2nc(-c3cnccn3)no2)C1
[b] COC(=O)CC1=NN(c2ccc(OC)cc2)C(=O)C1
[c] COc1ccc(NC(=O)CSc2ccc(F)cc2)cc1S(=O)(=O)N1CCCCC1
[d] COc1ccc(-n2nc3c(c2NC(=O)CCCl)CSC3)cc1
[e] C=CCN(N=Nc1cccc([N+](=O)[O-])c1)c1cccc([N+](=O)[O-])c1
Answer: b. COC(=O)CC1=NN(c2ccc(OC)cc2)C(=O)C1
