Task: Answer the multiple choice question.
Question: Which compound exhibits a 11.134\% 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 additional words.
Options:
[a] COc1ccc(COC(=O)C2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)cc1
[b] O=C1c2ccccc2NC(c2ccc([N+](=O)[O-])cc2)N1O
[c] COc1cccc(NC(=O)C2CCN(S(=O)(=O)c3ccc4c(c3)N(C(C)=O)CCO4)CC2)c1
[d] CC1(C)C(=O)Nc2ccccc2N1C(=O)CN1C(=O)c2ccccc2C1=O
Answer: b. O=C1c2ccccc2NC(c2ccc([N+](=O)[O-])cc2)N1O
