Task: Answer the multiple-choice question.
Query: Which drug has a 16.506\% 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(CC(=O)Nc1ccc(C)cc1C)=N\NC(=O)C(C)C
[b] O=C(CNC(=O)c1cccs1)N/N=C/c1ccco1
Answer: b. O=C(CNC(=O)c1cccs1)N/N=C/c1ccco1
