Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.520\% 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 additional words.
Options:
(a) CCC(C)NCCOCCSc1ccc(Cl)cc1.O=C(O)C(=O)O
(b) CCN1CC2([N+](=O)[O-])CC=C(Cl)C([N+](=O)[O-])(C1)C2
(c) COC(=O)[C@H](CCSC)NC(=O)NCCc1ccc(F)cc1
(d) CC(NC(=O)c1cc(COc2c(F)cccc2F)on1)c1cnn(-c2ccccc2)c1
(e) O=[N+]([O-])c1cnc[nH]1
Answer: b. CCN1CC2([N+](=O)[O-])CC=C(Cl)C([N+](=O)[O-])(C1)C2
