Task: Answer the multiple choice question.
Query: Which compound has a -28.553\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: C[C@H](O)C(=O)C1=Nc2c(nc(N)[nH]c2=O)NC1
b: COc1ccccc1CNc1ncc(-c2ccc(F)cc2)n1C.O=C(O)C(=O)O
Answer: b. COc1ccccc1CNc1ncc(-c2ccc(F)cc2)n1C.O=C(O)C(=O)O
