Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.670\% 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] O=C1NC(Cc2ccccc2)c2nc3ccc(Cl)cc3c(=O)n2-c2cc(Cl)ccc21
[b] COc1ccc(/C=C2\CCC(C3CCCC3)C2=O)c(OC)c1OC
[c] COc1ccccc1-c1cc(=O)c2c(O)ccc([N+](=O)[O-])c2o1
[d] O=C(N[C@H](Cc1ccc(Cl)cc1)C(=O)O)OCC1c2ccccc2-c2ccccc21
[e] Cc1ccc2cc(C)c3nnc(SCC(=O)N4CCCc5ccccc54)n3c2c1C
Answer: c. COc1ccccc1-c1cc(=O)c2c(O)ccc([N+](=O)[O-])c2o1
