Problem statement: Answer the multiple-choice question.
Query: Which compound has a 2.895\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CCOC(=O)/C(C#N)=C1/C=C(C)c2ccccc2N1
[b] COCCn1c(-c2ccc(OC)cc2)cnc1SCC(=O)Nc1cc(C)on1
[c] NC(=O)C1CCN(c2c([N+](=O)[O-])cc(C(F)(F)F)cc2[N+](=O)[O-])CC1
[d] O=C(NCCSc1c[nH]c2ccccc12)c1ccc2c(c1)OCO2
[e] Cc1ccc(CNC(=O)c2ccc(N3CCC4(CC3)CC(c3ccccc3)=NO4)c(NC(=O)c3ccco3)c2)cc1
Answer: c. NC(=O)C1CCN(c2c([N+](=O)[O-])cc(C(F)(F)F)cc2[N+](=O)[O-])CC1
