Task: Answer the multiple-choice question.
Question: Which compound exhibits a 16.752\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(OC(C(=O)NCc1ccccc1)c1ccccc1)c1ccco1
b: COc1ccc(N(C)S(=O)(=O)c2cccc(C(=O)NCc3ccc(C)cc3)c2)cc1
c: CC(C)c1ccccc1NC1=CC(=O)CC(C)(C)C1
Answer: a. O=C(OC(C(=O)NCc1ccccc1)c1ccccc1)c1ccco1
