Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.543% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: NC1=NC[C@H](c2ccccc2)N1CC1CCCCC1
b: CCOc1ccc(Cl)cc1S(=O)(=O)N1CCC(C(=O)NCc2ccco2)CC1
c: Cc1cccc2cc(CN(CCc3ccccc3)C(=O)N3CCOCC3)c3nnnn3c12
Answer: a. NC1=NC[C@H](c2ccccc2)N1CC1CCCCC1
