Task: Answer the multiple-choice question.
Question: Which compound has a 0.228\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(CSc1nnc(-c2ccc(O)cc2)n1Cc1ccco1)c1ccccc1
b: CC(C)(C)OC[C@H](NC(=O)C1CCN(C(=O)OC(C)(C)C)CC1)c1nnc([C@H](Cc2ccc(OC(C)(C)C)cc2)NC(=O)OC(C)(C)C)o1
c: Cc1ccc(NC(=O)COC(=O)CCc2c[nH]c3ccccc23)cc1[N+](=O)[O-]
d: CCN1N=C(c2ccccc2)CCC1=O
Answer: c. Cc1ccc(NC(=O)COC(=O)CCc2c[nH]c3ccccc23)cc1[N+](=O)[O-]
