Task: Answer the multiple-choice question.
Query: Which compound exhibits a 16.891\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) Cc1csc(N(C)C(=O)CSc2nnc(COc3cccc4ccccc34)o2)n1
b) CC/C(C)=N/Nc1cccc([N+](=O)[O-])c1
c) O=C(CCNS(=O)(=O)c1cccs1)N1CCc2ccccc2C1
Answer: b. CC/C(C)=N/Nc1cccc([N+](=O)[O-])c1
