Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -6.832\% 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] COc1cccc(C2(O)CCN(Cc3ccncc3)CC2)c1
[b] O=C(Cc1c(Cl)cccc1Cl)OCC(=O)N1CCN(C(=O)c2ccco2)CC1
[c] O=C(NC1CCCCC1)c1cc([N+](=O)[O-])ccc1N1CCCCC1
[d] CCc1nc(SCC(=O)Nc2nnc(CC(C)C)s2)n[nH]1
[e] O=C(CNC(=O)c1ccc(Br)o1)Nc1ccncc1
Answer: c. O=C(NC1CCCCC1)c1cc([N+](=O)[O-])ccc1N1CCCCC1
