Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.646\% human ether-à-go-go related gene (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) CCOC(=O)c1ccc(NC(=O)CSc2nc3c(c(=O)n2C)SC(C)C3)cc1
(b) O=C1c2ccc3c4c(ccc(c24)C(=O)N1c1ccc2ccccc2c1)CC3
(c) COc1cccc(C(=O)Nc2cc([N+](=O)[O-])ccc2N2CCN(C)CC2)c1
(d) COc1cc(/C=N/NC(N)=O)cc([N+](=O)[O-])c1O
(e) CCOC(=O)C1=C(C)OC(N)=C(C(=O)OCC)C12C(=O)Nc1ccc(Br)cc12
Answer: e. CCOC(=O)C1=C(C)OC(N)=C(C(=O)OCC)C12C(=O)Nc1ccc(Br)cc12
