Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 5.093\% hERG inhibition at 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(COc1ccc(Cl)cc1)Nc1nc(-c2cccs2)cs1
b. O=C(COc1ccccc1)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
c. CC1=NN(c2ccc([N+](=O)[O-])cc2)C(=O)/C1=C\N(C)C
d. CSc1ccc(/C=N/NC(=O)CNc2ccc3ccccc3c2)cc1
Answer: c. CC1=NN(c2ccc([N+](=O)[O-])cc2)C(=O)/C1=C\N(C)C
