Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.210\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CC1=[N+]([O-])C(C)(C)N(O)C1(C)C
b.) Cc1cccc(Nc2n[nH]c(C)c2[N+](=O)[O-])c1
c.) C=C1Cn2c(nnc2-c2ccc(Cl)cc2)S1
Answer: a. CC1=[N+]([O-])C(C)(C)N(O)C1(C)C
