Problem statement: Answer the multiple-choice question.
Question: Which compound has a 7.750\% 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 other words.
Options:
(a) CCN(CC(=O)Nc1ccccc1OC)C(=O)CN1C(=O)NC(C)(c2ccc(C)cc2)C1=O
(b) O=C(CSc1nnc(CNC(=O)c2ccccc2)o1)NCc1ccccc1
(c) CN1CC2(C(=O)c3ccccc3)CN(C)CC(C(=O)c3ccccc3)(C1)C2
(d) O=S(=O)(/N=C(/Nc1ccccc1)c1ccccc1)c1cccs1
(e) O=C(O)c1cc(-c2cccc([N+](=O)[O-])c2)n[nH]1
Answer: e. O=C(O)c1cc(-c2cccc([N+](=O)[O-])c2)n[nH]1
