Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 11.313\% 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) O=[N+]([O-])c1cccc(NC2=NCCC2)c1
b) COc1ccc(CN(CCC(c2ccccc2)C2CCOC(C)(C)C2)C(C)=O)cc1
c) O=C(c1cc(COc2cccc(C(F)(F)F)c2)on1)N1CCC(c2ccccc2)CC1
Answer: a. O=[N+]([O-])c1cccc(NC2=NCCC2)c1
