Task: Answer the multiple-choice question.
Query: Which compound exhibits a 15.620\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C1ON=C(c2cccc([N+](=O)[O-])c2)/C1=C/c1ccc(O)cc1
b Cl.NCCc1ccc(O)c(O)c1
c CCCCN(c1ccccc1)S(=O)(=O)N(C)C
Answer: a. O=C1ON=C(c2cccc([N+](=O)[O-])c2)/C1=C/c1ccc(O)cc1
