Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.671\% 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 other words.
Options:
a: O=C(NCc1ccccc1)c1cc(-c2ccco2)on1
b: COC(=O)C1=C(c2ccc3ccccc3c2)C[C@@H]2CC[C@H]1N2C(=O)NC(C)C
c: O=C(CSc1n[nH]c(-c2ccco2)n1)Nc1ccc(Br)cc1
Answer: a. O=C(NCc1ccccc1)c1cc(-c2ccco2)on1
