Task: Answer the multiple choice question.
Query: Which compound has a 1.657% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cn1c(=O)[nH]c(=O)c2c1nc(Br)n2Cc1ccccc1F
b: COc1ccc2nc(C)cc(SCC(=O)N/N=C/c3cccc4ccccc34)c2c1
c: O=C(COc1ccc(Cl)cc1)Nc1nc(-c2cccs2)cs1
Answer: a. Cn1c(=O)[nH]c(=O)c2c1nc(Br)n2Cc1ccccc1F
