Task: Answer the multiple-choice question.
Question: Which drug has a 16.199\% 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: CCOc1cc(/C=C2/C(=O)ON=C2C)cc(Br)c1O
b: Cc1ccc(NC(=O)N2CCCC2)cc1Cl
Answer: a. CCOc1cc(/C=C2/C(=O)ON=C2C)cc(Br)c1O
