Task: Answer the multiple-choice question.
Query: Which compound exhibits a 10.327\% 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)CCCSc1nc2ccccc2s1.O=C(O)C(=O)O
[b] COc1ccc(C2(c3ccc(OC)cc3)NC(=O)NC2=O)cc1
[c] O=C1NC(=O)c2cc([N+](=O)[O-])cc3cccc1c23
[d] COc1cc([N+](=O)[O-])ccc1NC(=O)NCC1CCN(Cc2ccc(Cl)cc2)CC1
[e] Cc1cccc(NC(=O)CCCSc2nc3ccccc3[nH]2)c1
Answer: c. O=C1NC(=O)c2cc([N+](=O)[O-])cc3cccc1c23
