Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.137\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccc(CNc2ncnc3cc(OC)c(OC)cc23)cc1OC
[b] CC(C)(C)OC(=O)NCCCC1=CC2=CC(=O)C(C)(OC(=O)c3ccc(Cl)nc3)C(=O)C2=CO1
[c] NC(=O)CC(NC(=O)Cc1ccc(Cl)cc1)c1ccc(NCc2ccccc2)c([N+](=O)[O-])c1
Answer: c. NC(=O)CC(NC(=O)Cc1ccc(Cl)cc1)c1ccc(NCc2ccccc2)c([N+](=O)[O-])c1
