Task: Answer the multiple-choice question.
Question: Which drug exhibits a -18.502% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ccccn12
b) Cc1ccc(Cl)cc1OCC(=O)NCCOC(=O)Nc1sc(=S)n(C)c1C
c) COc1ccccc1-c1c(C)oc2c(CN3CCCCC3C)c(O)ccc2c1=O
d) CCn1c(Cc2ccc(OC)cc2)nc2ccccc21
e) CCCn1c(C)cc(/C=C(\C#N)C(=O)OCC(=O)Nc2cccc(S(N)(=O)=O)c2)c1C
Answer: a. Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ccccn12
