Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.751\% 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) O=C(O)c1ccc(CSc2nnc(COc3ccccc3)o2)cc1
b) Cn1c(=O)n(CCc2ccccc2)c(=O)c2c1nc1n2CCCN1c1ccccc1
c) O=[N+]([O-])c1cccc(C=Nc2cccc3ccccc23)c1O
Answer: c. O=[N+]([O-])c1cccc(C=Nc2cccc3ccccc23)c1O
