Problem statement: Answer the multiple choice question.
Query: Which drug has a 15.490\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCc1cc(Br)ccc1N1C(=O)C2CC=CCC2C1=O
[b] O=C(CN1CCCc2ccccc21)N/N=C/c1ccc(F)cc1F
Answer: a. CCc1cc(Br)ccc1N1C(=O)C2CC=CCC2C1=O
